Needed: website plus optional iphone, BB, and android apps

Website will need to allow two different kinds of user accounts/profiles to be set up: 1. the end user- consumers 2. businesses Business user interface should allow them to fill out a few fields. All of this information should then be aggregated into a post in a stream of other posts created by other businesses. The business users account will also include the ability to hold credit card information for monthly billing that can be turned on/off The end-user should be able to view all of the deals posted by businesses who are within their zipcode. I would like these users to also be able to sort this stream in multiple different ways as well as search through the posts. The programmer should also be able to provide the design/graphics. I have some pretty detailed slides laid out in PowerPoint but graphics, as well as logo should be handled by the company contracted. Additionally, I would like to see options in the bid for smartphone apps (breakout cost of each for Iphone, Blackberry, and Iphone). Smartphone apps should use location devise of phone to aggregate posts rather than zipcode.
