Product configorator for Proposal

We need a web based responsive proposal solution with configurator. There are too many variant for each product. It will used for industry but i want to give an exapmle for understanding. Let's think about selling a car. A salesman should select variables step by step like below, Color: white, black, blue.. engine: 170 hp, 220 hp... fueloil: benzine, diesel type: hatcback, sedan, cabrio or coupe, tire rim size: "17,18.... sunroof : yes/no ..... As you see There are a lot of parameters and variables to create a product. In addition some cluster elements cannot match those in the other cluster. For example if you choose a diesel engine you can not 220 hp, or if you choose cabrio you can not choose sunroof. So There should also be a interface where you can select incompatible group elements. When you finish to configure the product i need to see price and also image. we will support all images of items. You need to consider what kind of variables need to image changing, if you change fueloil image is the same but if you change color or sunroof feature the image must change. I have to follow customer information and previous offers. ıt's not a big CRM so i don't need to keep sales activities, just customer information (name, adress, phone,e-mail, authorised person, tax number etc.) and proposals that can be edited. (date, status,amount, customer, salesman, explanations, sales condutions and of course product details) The proposal must support I need to keep also my company information that need to prepare proposal: company name, company logo etc. Salesman can prepare and send e-mail as pdf. We request that the software with source code. And we also want your support. Thanks.
