>>129289003000 pesos per month (~€125/month). It's just around minimum wage (which is currently around 150 pesos/day in Mexico). It's not a lot, but it's enough to satisfy my basic needs (I spend about ~$1500 per month on food, gasoline, and various other things, so I could save almost half of what I earn that way).
I hope the ERP thing works well for you and that you'll be able to find somebody who can complement the role you choose very well.
Anyway, have you thought about what kind of role you might like to play?
