We need a consultant to advise on our seo and online marketing

We run an online flooring business which is doing well but we haven't put as much time and effort into marketing online as we should. We'd like to speak to someone with the expertise and experience to advise on what we should be doing, with seo, email, advertising etc to improve sales. We don't want to put someone or a monthly retainer or anything, just suggest some sensible strategies we could carry out ourselves. Thanks
