Part Loan Wanted

I am currently looking for a part loan. I started riding at 13 and am now 28. I was a member of a yard until about a year ago and I have just started some lessons to get back into it after a confidence knock. I am now building my confidence back up and would love a loan horse for 1 day a week (weekend) to carry this on. I am able to walk, trot and canter but am just about to start to learn jumping. I’m about 5ft6 and weigh about 11 and a half stone so am ideally looking for 15hh plus to account for my weight. It would be beneficial to have a safe confidence giver that I could school/hack out. The one thing that is a definite dealbreaker is bolting as this is what knocked my confidence! I am happy to contribute financially/yard duties. I am from Eastleigh, Southampton so looking around this area but I do drive. Please feel free to ask any more questions as this would be my first loan so am new to this. Thanks in advance.
