500fastcash

I have a payday loan with 500fastcash, Red Cedar Services Inc.(online lender) It was for $600 and I have paid a total of $540 back with none of it touching the principal, so at this time I still owe $780 with the fees. I have been working very hard to clean up my debt and am working with a very good consolidation group, however they do not work with 500fastcash. I have been doing some research and I see a lot of information regarding this group being illegal to operate in the US. I live in Texas and I have not been able to find exact information regarding if this company is licensed in Texas or not. I have fallen into the payday loan trap, like many others and am behind in every day bills. I can not keep paying these people and survive at the same time. I have not defaulted with them yet, but I do not have the money to give to them on my next payday. Is there something I can do to work with this group so it does not turn into a nightmare? Any advice on how to proceed would be greatly appreciated.
