Set-up SobiPro 1.2.1 to have SEF URLs

Need a freelancer to set-up SobiPro 1.2.1 to have SEF URLs. I have created all the SobiPro sections and categories entered but so far only created 2 listings which are both in the same category. Hopefully this should be enough to demonstrate that. This means remove numbers from URLs to achieve www.d*m**[login to view URL]"section name"/"category name"/"listing name" I don't have any 3rd party SEF extension installed such as sh404 or aceSEF.
