Can anyone recommend a reputable search engine marketing company around Boston area?

I know there are a lot out there, but I just need someone or an organization who's from my area as well. Knowing that give me the feeling that I can trust them. Thanks!

I don't get the reasoning that shorter distances increase trustworthiness but if that works for you, do a web search for "SEO Boston" and choose either the nearest or the one that made it to the top of the list depending on whether trust or performance is the higher priority.
