Beta testing of site, SEO of phpBB and overall SEO review

The job I have outlined here has a couple different pieces to it. First of all would be an install of SEO mods to phpBB on an Oscommerce page already mod'd with it inserted. The second would be an overall review of the SEO mods in place and to modify where necessery to improve any SEO modifications. The site already contains seo urls, dynamic and header tag generator, custom seo mod to the article system, review system the events system needs SEO for the titles as well. The site has a lot of custom code... and before I can dedicate night after night... day after day of work into adding products and content... I must make sure all the code meshes. This would require using every feature of the FRONT and BACK end to make sure there are no database problems. Final payment would be received after a week of testing on my own to make sure all the bugs are worked out.
