We have our own PHP OSCMax shop that can be downloaded with our hosting service. We have already customised the master script and added new contributions ourselves as well as WYSIWYG header, main page and products editing.
We have a customer who wants his own graphically customised version of this shop to sell window blinds. There a number of different products and product variables and we want to present the customer with an easy to understand spreadsheet so that he can type in his products and product variables for upload to the database using EasyPopulate.
The shop will need customised graphics (but product images will be supplied by the customer) and an instant quote form for customers to enter dimensions etc and produce a quote before they decide to order or not.
