Replacing a GC midway through a project

[Tatiana K.]

Hello to all the brilliant BP'ers out there, hoping to get some good advice on an uncomfortable (albeit not uncommon) situation. 

We bought a duplex, decided to gut-remodel and hired a GC to do the job. We signed a contract, complete with payment schedule and scope of work, for pretty much the entire thing from demo on the interior/exterior, all the way through finish work, kitchen/bathroom install, plumbing, electrical, windows - everything. So far they've done demo and about half of the framing and we're very unhappy with the work. The GC is never at the site, his foreman is rarely there and when he's there he's not  directing the guys, and the workers are not familiar with or invested in the project whatsoever so we're getting very very subpar work that requires a lot of revisions and constant oversight.  

Bottom line is we want to fire our GC and go with another company, but we've signed a contract that doesn't have a termination clause (rookie mistake). We've paid for materials, demo interior, demo exterior and the next stage is the framing which we don't want to pay because the work is so poor. Any advice on how we might be able to escape the contract without losing our funds? Wanted to see if anyone has dealt with a similar situation or might know a good construction lawyer in the LA area. Any advice would be greatly appreciated!
