Since html is relatively easy, anyone can hack together a wen page. You just need to interview potential developers until you find one that communicates well, has some examples to show you, and can explain why the principles they used to develop their pages (ie, why did you use a menu bar at the top of the page vs using a menu bar on the left hand side? Why this combination of colors.)
SEO is not worth the money if there is not a solid web presence to where people can be directed. Sending customers to a landing page is a waste of money (and IMHO, SEO is a waste anyway).
It is just like hiring anyone else. Interview until someone feels right. You might consider checking if any local colleges have computer science programs. They may have grad students that might be interested in helping out, and they will be considerably less expensive.
And finally, you get what you pay for.
