Daimond / jewelry Club & e-commerce

Hello there, I want to create a website as a club for lapidaries, a Trade community and a forum , ability for users to list their gemstones or jewels and bids on them, Receive alerts, notification, news and mass email . designing should have easy management and ability for online payment for registering fee ( like moneybookers, paypal, egold,...) for functions and example please take a look at [login to view URL] [login to view URL] these sites are good but lack of quality , i need an elegance temlate and design, also as i have talked to some other designers i would like to know some issues. 1.i prefer to use Vbultin for forum but some how tables and data base should match to other sections of site if it is impossible other type of forums would be accepted 2. the ability for users to upload images of their gemstones or certificate and bulk in excel format, so the list their stones, or jewelries 3. this dynamic site should have ability to get change as i prefer time to time, maybe i would add/remove a field in any section or in search options for stones. 4. i need some help for the content you can copy some basics from similar sites like specification for searching diamond and the sections but as i want a fresh job the whole thing should be different. 5. i need to know the final cost of this project ( i don't care how many programmer and designer work on this please quote me the final price for finishing this site) 6. I have bought dedicated linux server so the design should match with it also can you advise me if possible you mix java with php for design? 7- my site would have these main sections, E-Commerce to book orders or direct payment ( which might required some online payment like paypal and moneybookers and credit card...etc), Trading forum and discussion, listing and searching option ( compatible with excel or access input & output but search options should support all kind of gemstones with their specifications for search and sorting which it can be divided into Diamonds, Colored Stones, pearls, Semi precious stones, jewels, watches, antiques..) , main body with newsletter and educational & download section . also a gallery for each user so all users would have their own virtual gallery. My site would accept users by subscriptions which I would indicate an amount for their membership so all module and scripts for payment should be available (credit cards, paypal ,check, bank transfer, moneybookers, and ...) all these sections should work with one data base also the ability of daily back up for database ( FTP and Email back up). 8- my designer should have experience in this field and this type of websites, so if you quote me please advise your ideas about above requirements and also quote me a fair price, a sample of previous job done by designer is necessary. Thank you, Farshid, [login to view URL]
