Architectural design

Need a blueprint for website which combines major elements of c2c & c2b segment. Examples of sites are below. 1. c2c a. [login to view URL] b. [login to view URL] c. [login to view URL] 2. c2b a. [login to view URL] b. [login to view URL] (Feel free to add more to examples or provide link to similar work) This is Phase I, pre-development, pre-coding stage project. - You should be able to architect the website in a smooth & convenient work flow. - We need the web site layout & database design. - We need workflow & process flow document. It should be detailed with database design, so as it can be used by development team as blue print to build the website. - Site layout design should be very pleasant to eyes and minimal colors – think google or craigslist. - Should use Ajax, so user doesn't has to click too much back & forth. If your company is winner & has capabilities for developing submitted site, we will prefer to retain same company. So Phase II may go to same company doing Phase I, provided that all criterias are met. Please submit some samples of related work.
