How do I get into an in-house job?

It's always been my goal to move in-house, and I'd like to ask how I can make that move in my situation.

A bit about me since that seems relevant. Currently in my 4th year. I graduated middle of the pack from a top 30 law school, did ID for a bit before moving into debtor's bankruptcy for a few years. I'm a bit past a year into a mid-size creditor's firm now. I run the day-to-day of our consumer and commercial collections practice. I do work for a few banks/lenders and have some good contacts. I'm good at what I do and my contacts seem to be happy with my work.

That all said, it seems to me that my best shot at finding an in-house job is at a bank, especially the banks I have good contacts with. My question is: where do I go from here? I know I'll probably need some more time in the saddle at my current job, but while im biding my time, what experise in other topics can i be building to make myself more marketable? I know they don't need collections attorneys since banks outsource that work to firms like mine, but surely there's a way to make my expertise in this area marketable.
