Mobile development -- 2

I need an Android app. I would like it designed and built. I want an app that brings business and people together as well as ability to post and bid for jobs or apply for position. There should be filter button that allows users to filter business or jobs in a specific country. Persons can the bid for jobs posted by employers or businesses. Users or Business will also be able to add the profiles and has the ability to send updates about their business to followers. Users will also have the ability to write reviews of others and select a skill set. Users can also create groups and send messages to other users but not to businesses.
