Please see below on my requirement and if you are interested, please reply me accordingly.
1) I am not looking for an expert to build a group buying website from scratch. I already have a working copy myself. But i would prefer you own one so that whatever customisation i required, you can work on it effortlessly (since is your script in the first place, i assume you have full knowledge of the script).
In order that i know you own a working copy. Please indicate this words anywhere in your group buying website homepage. "This copy belongs to me". When you done that, send me your URL for my verification
2) I have a set of customisation needed. I will only share my customisation requirement with selected developer only. (only those who can provide point 1 above) After sharing my requirement, you can review my work required and quote me accordingly.
3) 1 of my customisation requirement involved Paypal API. You need to be an expert and have experience using the API provided by Paypal. I understand that your existing working copy of group buying website already have paypal integrated but i will need further customisation. Here i am assuming that your working copy paypal integration is similar to groupon.
4) I will be implementing this project in phases. This project will serve as phase 1. And there will be multiple phases thereafter So i prefer someone who has history working in freelancer for a period of time. And is ready to commit a long term working relationship with my team.
5) The copy that i own is from uniprogy. So if you are also an expert in customising couponic, you can also let me know. Or if you own other script and are comfortable in those, please let me know as well.
