Zen-cart Modifications

I am currently setting up a website using zen cart. I require some minor modifications done as I not a very technical person in php. 1)All forms must have CAPTCHA functionality. This includes review form, tell a friend and contact us page. I have however managed to add a CAPTCHA feature to the create account page using the main downloads from zen cart but having issues with adding on other forms. 2)The contact form must show a subject field as well. 3)During account creation, hide telephone number field status must be enabled or disabled in admin control panel. If it is disabled, the telephone number field will not display during account creation. 4)There should be a feature in control panel to display products from all categories on homepage. I have set 2 categories, i want items from both categories to displays on homepage. All the above changes must be shown on overwriting the original files with new ones. I also require some basic documentation. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
