I agree with Baykus. If you're looking to leverage more of your MBA skills, then a natural progression from the IT world is in consulting. Combination of your IT heritage together with your MBA would seem like a good fit at the likes of Accenture, CapGem, Deloitte, BearingPoint etc. At least there's the career progression, opportunity to use your MBA, and associated pay increases.If you're looking to get into investment banking and the city, then I think that's a larger shift and a lot more difficult (especially if you don't know what equities are derivatives are - very surprising given you claim to have done an MBA ???)But it also sounds like you've been exploring the marketing arena (social media, SEO, etc). In which case why not explore digital agencies/consultancies such as Sapient, Accenture Interactive, LBi, EMC Conchango?
