Create Joomla site with extensions

Hello, I am a hosting and domain provider, and do receive regularly requests for coding work, as well as design and SEO. So, bidding on the following project could always be the key to a longer lasting relation. Work: - create and deploy on final server a Joomla site with extensions (joom fish, virtuemart or similar, some smaller utilities) - Theme/template is already bought - doing all work under the rule of SEO friendliness - doing SEO when project launches (domain selling site)
