I have a client that offers private investigation services. He'd like me to be his web/online marketing agent, wherein I do everything for his websites and online marketing in exchange for 10% of his online sales.
The problem: Most of his actual sales come by way of cash, check, or Western Union online.
The Question: How can we implement a system that would be relatively automated, which would allow us to track the clients that came to him through his websites?
Thanks so much for any suggestions.
