Wanted To Buy Beginners Trail Riding Mule

Want to buy an extremely quiet experienced trail riding Mule 14hh to 15hh prefer gelded (age not an issue) I have over 50 years experience as a trail horse rider (but was born with physical disabilities that significantly impact my mobility including mounting and dismounting) and DO A LOT OF SOLO BUSH TRAIL RIDING IN THE MOUNTAINS and am happy just walking along trails although at times need to use roads that have considerable traffic including trucks and heavy machinery. Not sure what going price is for a one in a million mule BUT my bank accouunt would max out at $1,500
