Blog Customization from theme Template

We have a very nice Wordpress blog theme template purchased via ThemeForest called GEN20XX (you can go to ThemeForest's website and enter that in the search box to see it ... they are a .net domain). We have Wordpress already setup on our hosting account and the theme uploaded successfully via FTP. The dashboard appears successfully with the theme and options for it with our Wordpress login. We simply need it put together with our customization ... text, page's, advertisement boxes, hyperlinks, banner and logo. We will provide all images of exact size required to replace the template one. We are creating NO additional customization. Everything stays in the same place for now and all fonts, etc identical. We actually understand how to manipulate blog design but really are not expert at it and short of time/staff. We intend to put 2 additional blogs up as well ... just not part of this project post.
