ISO summer horse work (Cottage Grove)

Hello, i am in search of a summer job involving horses, i have been around them quite a bit this last summer and i do good with cleaning stalls, grooming, and i can ride to a certain speeds.
i can handle a pissy mare or gelding, i have a very soft yet firm hand, i am 12 years old yet i act much older.
i will do things on the weekends through the fall, winter, and spring, because of school i can't be there full time but i may be able to come out after 3pm on weekdays.
it would be nice to be able to get a ride out but i could drive out with my parents.
this would need to be in the south lane, london, cottage grove area.
