Repositioning keywords - SEO, PPC

We are a travel business slightly stuck in a keyword category that isn't growing, yet we also fall into another category that is exploding. We need someone with both marketing and technical skills to shift our website, and offering, into this growing category, so we pick up this increasing traffic, and take advantage of this market growth.

Imagine this will be a longer term relationship, as PPH is recommending a very low budget. To be discussed.
