That's fine, you don't need them to pay more than $10/hr. You only even need to earn say, $800 a month (I'm assuming you'd want a pickup truck to transport your mower and get around, so padding the $432 a bit) so if you worked 5 hours a week at the gas station for $340 then you need about 11 hours of $10 work per week for another $440 and you're done. If you have any savings, the current interest on $100,000 would alternatively give you $416 so you could just not work at all.
