online kitchen designer - repost

We are looking to create an online Kitchen Design tool for our online customers to use to create a graphical lay-out of their Kitchen/Laundry/Bedroom design, very very simular to this type of one: [login to view URL] This link is a brilliant example of the type of thing that we are after, it's very easy to use -No software to download for the Customer (which is what we want), just open page and start designing. we would also like a 3d view of the finished design utilising software already on windows or the option of being able to download required software by the customer We also want to get the 'List' report so that prices can be imported directly from our on-line site shopping cart ([login to view URL]), creating dynamic pricing for the Customer, rather than asking them to email the design to get a quote. We already have the shopping cart done, The other thing with this example site is that you can't seem to save a job, so we would be looking at needing a 'save' option question. once the design is done a customer list can be databased by us . We will supply the Product graphics, it's really getting the software written and tested that we need. We also require the source code as part of the project. I hope this is enough information, Thanks Tom Armstrong this is not a build website post it is an add on to an existing site ,if you have not done this type of work before please dont reply ,no time wasters
