Add-On To Group Coupon Website

I need a dedicated, reliable, and experienced Cake PHP/MySQL developer to work with me on a Group Coupon website before it goes live - We need to do the following: 1- Fully Test the site for bugs and defects to make sure it is stable to perform its desired tasks 2- Change the colors of the site according to my requirements 3- Do some text editing according to my requirements 4- Add a payment Gateway 5- Go Through a Demo Together Note: I have bought the website a week ago, fully developed and functional per the seller, however I need an independent developer to go through it and test it for me. I will also need to customize the site based on requirements mentioned above. I have already created a logo and changed the domain name. I need to integrate the new logo and do some text editing and change the colors to match my palette. I will also need a Demo session to go through the details.
