custom posts to mobile view

Project details: I am using a wp theme that is not mobile friendly and need someone to come up with a solution. The individual property posts at [login to view URL] need to be very mobile friendly. Visitors need to be able to view full property post, login, bid, tap to call agent, view other properties by the agent. I have attached 2 screen shots showing how the posts are now and another showing what I want deleted or moved. Happy to answer questions.
