This is awesome, I've a marketing agency aswell but I only offer services in Spain. 1. The thing is that the average sale here is 6k per deal, and solar businesses have around 15% in net profit. I don't know how taxes work in the place were he does advertising, but here I need at least to do aorund 6x-7x in adspend to obtain the return on investment for my client. 2. Did he just does the ads under his brand and then after some qualification questions to the leads says something like... here is the best solar business for you in your area?
