Stable hand/rider/groom looking

Hi I’m a 13 y/o girl looking for a friendly yard in south-west London/surrey/Sussex area (ideally the 1st two options but I can also do Sussex). Could do weekdays (after school) and Sundays. Happy to do any jobs around the yard - mucking, grooming etc and am eager to learn. I’ve had a few years of experience and can canter, hack, gallop and jump small confidently. Would probably have an adult with me at first. Im happy to travel so it doesn’t matter too much if it’s a drive away. Please let email if I can help!! Thanks
