I actually found my boy on here! I saw his ad on google when I was searching for a new horse (my last girl just wasn't working out, she was a fruit loop). I had looked at several other horses with no luck, they were all either too small, too old, too expensive, or too far away. I wanted something that was 15hh+, 5-9 years old, within an hour away, level headed and my budget was $1,000. Skip met my standards perfectly, and then some. The only thing I would have changed was his color, he is a chestnut and I absolutely adore bays, Grullas, roans, and greys. Now, I wouldn't change anything about him. Chestnut has to be my favorite color now lol.
My only suggestion is to not settle for a horse. Don't let small things turn you away, but don't settle on the first horse that fits one or two of your criteria. I did that with my previous mare, and it was a pretty big mistake(and a huge loss of $2,600). It would have saved us time, money, and a few hospital bills if I would have said no, she isn't what I am looking for.
You seem to be off to a great start, good luck finding "the one"!
