I see the commission strategy as being a good thing only if a few conditions are met.
What a commission strategy does is basically provide employment for other people. Not full time employment, especially in your case, but you're trying to motivate people by paying them. For this to happen, you have to do two things.
1. Pay them enough to make it worth their while
2. Have a system where they can succeed enough to make the payment worth their while
If you offer something where the payout of $10 per month is only met with hours and hours of effort, then you're not likely to get many takers.
My theory, not that it counts for much, is to have a good and superior product, with a focus on a great customer experience. That way, anyone who experiences your service and your product will passively market you everywhere. Instead of enlisting people to go out and hunt down customers for money, you will be recruiting real life walking testimonials. And you'll be keeping 100% of your profit.
I'm not saying the the commission won't work, just that you have to make sure the commission process is worth it for other people.
And nothing is stopping you from doing both.
