I have an urgent requirement for experienced PHP developers and firms who have the experience with the following: - PHP - Javascript - Actionscript PROJECT SUMMARY: This is an indepedent music-related web site where members upload their audio and is available for registered users to purchase. The site is working as of now where members can upload pictures, and audio files. The payment component has also been added but needs further customization. I have had developers in the past who have left the project when it was half-way through. It works, but needs further improvements. Please be ready to demonstrate your experience with [login to view URL] Payment Gateway, Actionscript, and advanced PHP scripts. I DO NOT want cheap developers. DO NOT WASTE my time by bidding a generic bid. I want specific bids, and SHOW ME YOUR PORTFOLIO sites. Upon successful completion and payment, the code becomes my property and you will hand over all the codes to me, and not reuse ANY of the components for your other future projects for other clients. You will also need to sign the NDA prior to working on this project. Good luck and happy bidding.
