Create a Wordpress Template

Hello, I am currently after some customizations / modifications on my Wordpress site. The template than I am going to use is this one [login to view URL] My goal: I am trying to create a review website based on images, I will be requiring each user to either have a personal account or a business account upon registration. A custom Author page would be required. With the business account selected then the user should be able to add a shop logo / header to that page with a description about them and their service, they should also have a portfolio / gallery with all their images displayed it it. Like a personal studio. Users will need to be able to create new posts with images that will display not just in their own gallery but also on the front page like a news feed / latest posts. Users will need to be able to edit and change their own posts and also will need an easy form for creating the new posts with image uploaders, category selections etc. I will also require a widget that will allow users to search for authors, filter them by location / distance and rating. In each post i will need a contact for that will allow users to contact the author of that post directly about that image. Google map would also benefit here too. All these options should also be available for the author to set in their settings / parameters Many thanks Chris
