If you don't mind my saying, your reply to a reasonable follow up question seems brusque to the point of rudeness.
Still, it's a forum where cleaning professionals help each other out so my understanding of newbroom's query is that he's comparing your intended service provision against Servicemagic, Companeo and about a thousand telemarketing companies who will charge for leads but nothing else.
Your proposed business seems to involve a more complicated and expensive relationship and invites further explanation; if I can offer one piece of advice, responding to queries with " no need to clarify". "not going to do it for nothing" and "up to you" suggests that you and Dale Carnegie have very different views on sales techniques.
