I can't think of any places that would hire a 14 year old, at least around here. some places will when you're 15. But cutting grass is a good little job. You can do it just a couple times a week (depending on how many yards you want to do) and have the rest of the week off. Maybe do some work around the house for your parents, grandparents, or other family members for some money. I have a 13 year old sister who does that sometimes. I don't think I would sell any of your collection.. that would be that much you would have to get back.

Good luck!
