Customize Agriya Groupon Pro Software

I need someone that has in the past worked with Agriya's Groupon Pro software package. I need this DONE in less 20 days....I do have some leeway with a few of the functionality changes depending on which ones (ie we can do a 1.0 launch and a 2.0 update shortly thereafter) If you can't hit deadlines, DO NOT BID AND WASTE EITHER OF OUR TIME. You must have a team that can work on this (in case of illness, ect). I would prefer a DEDICATED team if possible You MUST have members that have worked on the previous Agriya software....we cannot afford any delays while someone it trying to "learn" the code. I would appreciate references for any Agriya projects that you have done and feedback since this is really not a "portfolio" thing. Thanks guys! I have a reasonable budget for the time and work we are talking about, so let's get it done.
