Designing Website like inkfruit.com

We want to design the website like inkfruit.com. We have all the necessary infrastructure, offices in India, Finance and all, but we are not well informed on the technical side so need persons to do it. We want the best platform, with all technical details and online store, with payment gateaway. The time frame for the project from start to finish we are expecting is 3 - 4 months. We want persons who can handle all the technical things and develop it. Please send us your proposals with step by step detials and how are you planning to implement it. Website features: - user friendly, - little different desing than this one in the example, - few places to put banners and google ads on all pages, - search all classifieds, detailed search, unlimited changeable categories (three levels depth), sort classifieds by name and price ascending/descending, go to the page, see all, news page, terms&conditions, about us, - (2) two languages, - two currency (INR /USD), - buyer payment (by alertpay debit/credit card secure payments), - buyer feedback system (positive, neutral, negative; with comments). User (buying options): - see all classifieds by user, - "Buy" button, - "I buyed" list, - contact seller by e-mail (website standard contact form with antispam CAPTCHA), - wishlist. Anybody can browse classifieds, contact seller by e-mail standard contact form (with antispam CAPTCHA) and see user feedback and all items. But only buyer who are members and they are logged in have option to click "Buy" button and left feedback to seller. After clicking on "Buy" button, item is automatically inaccessible to other users and marked as sold. Administrator options: standard (delete classifieds, contact members, ban members, change/delete feedbacks, place banners, posting news, etc.) This is first phase of website development. Next phase will be API system which will provide sellers to put their selling lists on own websites. So, I need long term and serious partner who have skills for this jobe. And many others later. Please, place offer only if you have experience and if you have already done some classified websites with similar features. Examples and suggestions are welcome. Thank you.
