2 Wordpress sites in one

I have the design mockups for a site that needs to go up. The site needs to be built using bootstrap css and as a Wordpress theme. Here's the tricky part: [login to view URL] and all of its folders will be part of wordpress theme #1. [login to view URL] will be its own wordpress theme. So to edit the site, both "[login to view URL]" and "[login to view URL]" would be valid URLs. The main theme will be custom, based on design mockups. The blog theme will be based off of a purchased version of the theme found here ([login to view URL]) with some minor customizations. I would like to have this done within 5 days if possible.
