Wordpress Prestashop Integration

I would like to integrate Wordpress into my Prestashop website. Wordpress will be on the same server as prestashop. We could set up subdomain or a folder to use Wordpress etc. there is a wordpress plugin that will help with some of it [login to view URL] Must maintain the same design as our site, can be in an iframe, but ideally not. Also must be set up to use permalinks for seo purposes and should integrate with prestashop, ie be able to select category pages that a post will show up in a sidebar etc. Our test site for your review is at [login to view URL] Thanks, we are on a strict budget, and are looking forward to working with you, must be completed in less than 5 days.
