I agree that the lack of an MBA, given your experience, is not likely to be a significant issue in getting into consulting.If you are happy consulting with a CRM, marketing, or related specialism then you're going to be well-set at the end of your current project.If you want to make a larger change, into a different type of consulting, then further study could be beneficial.Ultimately, if you can't afford an MBA at this stage then it's not something worth worrying about. I'm sure the Big-4 would be interested in you, as would a number of specialist consultancies - it just depends what your preferences are for working environment and types of projects.
