How can I get information on starting a answering service from home?

I have a disability I'm recovering from and I need to work from home. This is a good time for me to start my own home business. I have 19 years of call center experience and I feel as though starting an answering service from home is the way to go, However, I have no idea where to start. I do not have a lot of money but I do have the necessary equipment. I'm not looking to get rich quick or those so called home business opportunities that promises great wealth and are always asking for investments. I'm not interested in any multi-level marketing programs, buying a distributorship or selling any products. I'm not interested in buying into a franchise. I have read about people starting home businesses using their telephones but, they didn't give any details. Any suggestions will greatly appreciated. Please, only serious responses will help me. Thank you.
