Business credit card debt and legal action?

I need some good legal resources for being able to handle the substantial debt I've incurred starting up my business. I am in settlement with one, but I owe so many others that I am unable to pay until I finish settling this debt, and then I'll settle the next and so on. I have a few accounts that are in the Law Office of so and so. Do I need to call them back because they don't tell me who they represent on the voicemail. I live in Texas, so would need contacts familiar with small business debt. I tried a debt negotiation company, but those don't work for me and end up costing me more.
