Looking for Rider for Partial Lease in Los Altos Hills

Looking for a partial leaser to ride my 16H selle francais mare in Los Altos Hills at Westwind Community Barn 2-4 days a week. Ideal person would be intermediate/advanced rider that is looking to do some dressage and trail riding. She's well schooled on the flat with all the buttons, and great on the trails alone or with others. Comfortable gaits and fun to ride! Just turned 21 and still has plenty of spice and can get forward, but no funny business. Asking around $500/month give or take depending on number of days.
