Hang tight. Bring up your concern to your boss, and make sure they understand the implication of what you're saying (eg, that this is something you're ready to quit over).

Sometimes you draw the short straw in consultancies. Question is, is this a permanent short straw, or something that could change 3-6-9 months down the road? Working on interesting projects is where everyone wants to be, and there's a thing we call "paying your dues" ;) Have you paid yours?

My advice: First, have the above conversation. Assume for now that the situation is fixable -- from what you've said I can't see why it isn't. Next, start interviewing. Talks with recruiters are nice, but they'll blow smoke and make you feel like the most in-demand guy on earth with nothing to back it up. Get a few interviews and an offer in before you bail. No debt is great, but cashflow is king. I would hate to see you Office Space your curent situation and then discover that a fresh grad with 8 months of VBA experience isn't as marketable as you thought.

Bottom line -- be smart, take steps to get where you want to be, and keep cash flowing in.
