The general suggestion is to place main, important keywords in page title, header, in paragraph.  I suggest to starting off your title with prominent keyword rather than welcome to. Keywords you specify in your Meta keywords, description, heading tags of the body and in paragraph must relate each other in meaningful way. You should not focus on including keywords because you are targeting instead focus on creating content which is most relevant to service you provide.
