Website coding - Linux server (php?)

Currently I have a psd template for a site that I am about to extrememly makeover. My first question is, if I want to add a site search feature, does that get created in photoshop? Second, I want to create a member login feature at different levels, again, do these get created in photoshop or dreamweaver? Now for the hiring: I will need someone who can create a search feature for my site that is customizable to my layout, a membership login in that is customizable to my layout. The membership login needs to have an availability at differnt levels (if the user wants a free membership they can continue without paying, if they want a paid access membership they get redirected to paypal, then redirected back to the site). In addition, I am contemplating a stock and/or futures charting suite similar to [login to view URL]'s quality, and/or a quoting feature. ## 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.
