Our client wants a price estimate form to be put on the existing PHP website with a shopping cart facility so that their potential clients can get a price estimate directly on the site. There are different product categories and the selection has to be made in a 3 tier form structure where input values will come from all the three pages based on previous selections. Simple stuff, only looks a little confusing. Shopping cart facility is just to choose the products, no check out is required. The client also wants website redesign in oscomm or joomla and SEO work later if this goes well. Please bid if you have prior experience in above fields and can provide references.
