I need a good programmer to help me modify a few php scripts. This will be an ongoing project and could run several weeks. I will need someone who is available from 8pm to 12 midnight Phoenix, Arizona time (GMT-7) current time is 9:35am. I will probably need 5 days each week. Please bid based on each day's 4 hour block of time. At the end of the 4 hours, I transfer your funds to you via sl and we repeat the same thing each day. I'll give you a priority list of scripts that need modification and monitor the progress. 1st order of priority is building a shopping cart script into the website. next will be building a newsletter script into it. etc etc. The website is [login to view URL] and it has both a desktop and a mobile phone section. Please remember to bid based on your fee for a 4 hour block of time
