construction of e commerce picture framing,print websites

Ok can we get one thing clear, having already been ripped off by one freelancer, we have had to make it clear that we will not pay monies upfront in the hope you my or may not do what has been asked of you, so milestones will be 60% on completion of first website and 40% on completion of second site, (this is to stop the con men bidding) we are genuine and need these site's now ASAP. Due to prior let down We also have a lot more website work for the successful company and an on going SEO contract. We are looking for a skilled person or company to construct two website's, all design/layout work has been done and will be provided in ps4 format, so what we now require is someone to construct the frame work and workings of the site's which will need to include the following. 1. customer login in and retain prior orders details etc 2. photo unload and enlargement, also file check on max size/quality, also paper selection. 3. frame design section similar to the way [login to view URL] design section works. 4. full admin access by us, to which we will upload data ourselves ie frame style, mat's color type, glazing etc 5. full checkout and payment etc. 6. output invoice order etc. 7. all ownership rights to be transfered to us on completion. Both website's are the same in construction with small differences, being different names coloring, Layout, one being bias to printing other bias to framing but essentially the same workings. Each website will need to be constructed with SEO in mind. We plan to complete and test one site at a time. We are hoping to find someone to have a long term relationship with for ongoing development of the site's and others. It would also be good if you are able to carry SEO of the site's and again this could carry on long term under agreement, but not essential. It is proposed to start work on first site very soon after instruction. Please only price if you are confident you can do this! thank you for your interest and if you require any further info please do contact me wayne
