backend scripts2 - online product design, order placement, payment processing

PLEASE READ ENTIRE PROJECT BEFORE BIDDING. GENERIC MASS BIDS WON'T BE CONSIDERED; THIS IS A UNIQUE PROJECT AND REQUIRES A UNIQUE BID. THANKS! I'm relisting this project because of some great insight by some of the bidders here at GAF. I have a sign company for a client. Their signs range from real estate yard signs, to billboards, to banners, to flat storefront signs, automobile wrap, window perforated image, laminated vinyl, etc. They need a new website (will be running on Linux w/ Apache, PHP4.4), and i’ll need scripting to include the following: - WYSIWYG editor to allow customer to custom design a sign. Based on user’s choice of common dimensions (i.e. choice A, 4”x8”; choice B, 12”x18”, etc.), giving user a WYSIWYG editor, allow user a choice of colors, use common templates designed and uploaded by sign company or allow design from scratch, allow user to enter text to put on the sign, control over placement, give view of final product with option to submit or return to design. The file, once approved for production, is submitted (FTP or email) to the sign company for proof. (DESIGN FUNCTION SHOULD BE SIMILAR TO [login to view URL]), - popup or embedded calculator, to calculate cost based on variables given by sign company, but also based on customization by customer (i.e. for banner material, cost per sq.ft. is $12, for corrugated metal, cost per sq.ft. is $18. If the customer selects three 8”x”14 signs of a given material, how much does this total?) - fetch shipping prices from [login to view URL] based on user’s zip code and shipping requirements, weight and dimensions (PASS THROUGH FUNCTION SIMILAR TO www.48hourprint.com--check it out: three clicks into the order placement process, you have the option to fetch shipping rates) - May need secure payment processing (instant pay via credit card, possibly allow the option to “arrange payment with Sign Company” – allow sign company to approve an order for shipment based on special terms, maybe that customer is billed monthly or another special arrangment) I’ll probably set up the site in OScommerce, mainly for the login shopping cart, payment processing and customer tracking features, but a majority of the site will be your script. I'LL DO THE FRONT END DESIGN. THIS PROJECT IS MAINLY FOR THE BACK END PHP SCRIPTS FOR 1) THE "DESIGN YOUR SIGN" FUNCTION, 2) COST CALCULATION/PULL DATA FROM [login to view URL] (although it wouldn't hurt if it looks pretty!) Please if bidding, send links to similar projects you managed. thanks!!
