User interface

I have a new blog for businesses – in business. and I would like to add an option for users to add details of a business they have for sale and to be able to control the items that are listed – The items to be listed and included by users would be – price for sale, turnover, profit, location, business description, reason for selling etc. Is this possible please – I’d prefer to do this as a form type entry and not as just having a post by a user, so that I could have a page for other users to view that would list the businesses for sale – it would be great to be able to search on, say price, location etc.
