I'm wondering what a fair commission is to get contractors clients. I'm not talking a full on general contractor. Simply advertising, getting clients that need electrical, construction, plumbing, landscaping, etc work done and then turning those clients over to the contractor, nothing past that. General contractors charge about 15% of labour cost and usually 10-20% on material. I was thinking 15% on labour and nothing else? Considering i can get them many clients I shouldn't have a problem with getting cut out of the commission. Is 15 to high or to low?
