I'd team up with an
SEO that is a reseller, or pays out a nice commission. I've found the more things you try to focus on the less specialized you are at any one. And there is a shortage of companies that do search engine friendly design, without trying to dabble in
SEO while doing their clients a disservice. That being said you could read up on areas such as keyword density, then build a nicely optimized page and hire a link building company to build up the reputation of the sites. Cheers.
