I don't mind waiting years for a call,but I would probably have a problem paying and waiting years. Most of the guys I buy calls from that have a long wait contact me when my name comes up and I send payment and within a few weeks the call is in the mail.
One callmaker I buy from I pay in advance and within a few months I've gotten my call or calls. Thats about as far out as i care to go.
What happens to your money waiting that long if something happens to the guy or Life throws a curve ball at him? No Thanks that system isn't for me.
I'd wait and buy one off the classifieds or put up a WTB add in the call classifieds.
