I pay our gardener 300 pesos (about US $17) a day, which is the standard daily gardener rate for San Miguel de Allende. He comes once a week and works from 8 AM to 4 PM nonstop. He's very good at maintaining (not manicuring) our yard of 13-1/2 acres with that amount of time using both his and my tools.
In San Miguel de Allende, you pay more if workers come on a per day basis than you pay them if they work full time for a week.
