Big 4 Audit trying to transition to TAS/Valuations?

So within a week doing audit at a Big 4, I started looking for a new job. I really want to go into IB, but I know that given that I don't have any transactional/deal experience and didn't go to a target that'll be near impossible. So I've been looking into TAS (Transaction Advisory Services) and Valuations, but I'm hearing back from VERY few places especially considering the number of applications I've put out.

Just to give some background, I have a BBA and MS in Accounting at a school with a pretty distinguished accounting program, 3.6 GPA, have experience at bulge bracket bank wealth management, accounting/finance roles at major alternative asset managers/pe shops, and Big 4. I think it may have to do with the fact that I've only been there for 6 months?? But, I've hears people say they've stayed for that amount of time and got out.

DESPERATE for any advice.
