He agrees 100% but he's not willing to pay up front. He wants to see how many calls he gets first.
What do you say to someone like this? He's in a cleaning type business and he tells me his clients don't pay until he cleans, why should he pay me before he gets calls.
I know I can get him ranking for his keywords, but I have no real control over the number of calls he gets and I have no idea how many calls he would need to consider my services worth it.
