Building Supplies Company

I want to thank you and the Coley Team for the GSA Schedule training. The information was on target. Your Team Members were very helpful in answering our questions and providing us sound direction. As for the service throughout the process, our consultant did an outstanding job communicating our position with the negotiators and contracting officers while keeping us informed on the process and our progress through that process. This minimized any surprises and prepared us for the various phases. Contracts Administrator

IT Services

Please extend and accept my sincere appreciation for how well your team of GSA Schedule consultants makes our jobs here easier, if there is ever a problem you are on it immediately. Your firm has been a fantastic resource for years and I well expect years more, you know that I always tell everyone call Dan and Jack and always will! Thanks again for doing more than just your job! President

IT Solutions

Thanks for all your help. We signed on with your company a few weeks after a friendly competitor of ours had contracted with a different company–and they are still not close to obtaining their GSA contract. I was in a meeting with them yesterday and there were a few shocked faces when I told them that we’d already obtained our contract. To top it off, they paid roughly 30% more than we did. Feel free to add my name to your list of satisfied clients! President

Jack, I had to take a minute and say thank you. Daniel and his GSA Consulting team has been a wealth of help in getting ready for my review, your service is fantastic and I wanted to say thank you. Also, your office receptionist is always so nice when she answers the phone, takes messages, and tracks down Dan for me. Thanks for being such responsive professionals. President

Jack, Dan: Thanks so much!!! Your team is simply the best.  There is nothing like coming through for a customer at the 11th hour and that’s what you’ve just done for us. I can’t adequately convey the peace of mind it gives us to know that we can turn to you and be assured of getting sound advice. CEO

Your GSA Schedule consultant was ever so helpful in assisting us in obtaining our renewal for our GSA. She was very courteous, prompt and knowledgeable when it came to handling our request. Manager


You have been fair and ethical in your business relationship and very upfront in sharing relevant information to assist us in decision making. You are appreciated! President

Staffing Services

I wanted to let you know that I just finished the audit with GSA and I was able to answer and identify everything that they asked me. I would like to thank you for all of the assistance you gave me to get ready for this. The eBinder packet and audit guard report were extremely helpful, and basically the reason that this went so smoothly. I was able to get all of the documents mentioned compiled and ready before she arrived. I was actually prepared! Manager

Billion Dollar Systems Integrator

We had our GSA Schedule compliance visit and passed with a perfect score. This is due in large part to the efforts of the Coley team leading up to the visit and even made yourselves available by phone during GSA’s visit.  We are certainly glad to be working with your team and appreciate their diligence in keeping us straight. CEO

Water Purification Solutions

I have had the pleasure of working with Coley since 2004.  In that time, Coley helped us both obtain our GSA Schedule and  its renewal, as well as assisted us in strategic planning and writing winning proposals that resulted in several different contracts.  These were all due to the knowledgeable staff at Coley.  We are also on contract  with Coley for GSA Contract Maintenance, a decision made after we discovered the headaches of GSA compliance and reporting on our own, and turned to the Coley professionals, a wise decision that gives us the security of knowing that our contract is compliant with all requirements and up to date. In the past nearly 10 years, Coley assisted us in building our business through identifying upcoming Federal opportunities that were a good fit for us as well as through targeted e-mail campaigns that resulted in qualified leads. Whenever I have any questions or issues that arise, I am able to contact someone at Coley and get definitive and concise answers. RFQs and bids that are submitted are done very professionally. Every employee that I have spoken to over the years is very professional and well-informed.  When there are deadlines that must be met, Coley is usually reminding me that I need to work on tasks rather than the other way around. I would highly recommend Coley to anyone interested in contracting with the government. General Manager
