Art co-op, subscription, ecommerce art website, .mobi abled.

I am developing an art based website that among other things will be able to host other art dealers galleries and their available merchandise/art works for sale. The subscription based gallery owners will be able to create their own intuitive home page from a simple to use control panel that allows them to present images and related descriptions to those images (i.e. size, medium, year created, artist name, history of the work...) They will need to find/select a given artists name from the hundreds of artists whose names and biographies... are part of the sites sphere of artists under management/consideration. The website will have varying levels of subscription options ranging from free registration with somewhat limited access to various content to "diamond" partners who will have access to all areas of the site in a generally unlimited fashion. The site will take payment from subscribers via secured credit card info... The site is proprietary and all work in the form of code writing or otherwise bid out will be created for the exclusive use/benefit of the site and/or its owners... and cannot be ever shared or distributed and mutual non-disclosure agreements will need to be signed stating developer(s) and their affiliates... will not share/distribute any information between the agreeing parties... Various areas of the site will be secure (for certain paid subscribers only) and perhaps one paid subscriber will not be able to enter an area that another paid subscriber can - this due in part because of varying levels of paid subscriber partnership or otherwise. I need separate control panels that will allow registered members to contribute their information such as museums listing their museum in a museum directory and art restorers listing their art restoration business in an art restorer directory and framers listing their framing business in a framers directory and so on... The dealer control panels must allow for them to include a logo of their business, a one-liner on their main interests, contact details, their art work and its related details (from drop boxes... that give them options to choose from and so on. I will (have begun to) create all pages in photo shop to be produced and supply all images for the site and all content as well - including word docs. and the like. The pages are simple clean and self explanatory. The site will be set up to receive historical information on the artists in the sites database form others in an easy concise way. The site is unique and proprietary in its own right but there are numerous websites where developers considering this project can take inspiration from and get a better idea of what the site seeks to achieve. The following are sites to look at when considering this project: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] and the list goes on... Although the website in consideration is vastly different - some of the data entry will be similar in that the site in question is art based as well and among other things seeks to attract art galleries, museums, collectors, investors... to the site as either registered users and/or subscribers...
