Zen Cart - modifications / changes

I will only consider experienced zen cart programmers for this project with excellent php skills. Please show me your portfolio or I won't choose you! Must be done within 4 days - IMPORTANT Some of the requirements listed in the attached *may* have already been fixed, you will need to look because I don't know. Another programmer started but didn't finish and according to him he completed some but didn't tell me which ones before he disappeared. Budget will not be adjusted if they are fixed so you can make an extra profit if it's the case! This is a food catering web store. I will give you the url in PMB. Make sure you know you can fix _everything_ on the list before you say you can do it! Budget $400. Escrow will be made after I see progress and feel comfortable with your abilities, so please don't ask. I will reserve the right to hold back funds ($20/day) if you do not complete this project within the 4 days as specified. So please make sure you have the time to work on it before bidding.
