Dan,

We do accept credit cards.  We have found this to be very helpful in only certain situations.  The first was when a client of mine was going out of business said they would pay me by credit card and at that time I did not accept them.  Well, to my sadness they did fold up and go out of business, and yep you guessed it, I DID NOT GET MY MONEY.  Now I inform my clients who are behind, or about to close, they can pay their debts by credit card.  We do have small success at this time and YES I do feel that it was worth it, but only if the amount to be charged is worth the monthly fees.
