Sorry, can't help and hope you get a serious reply soon. I just could not help smiling trying to imagine what my made to measure saddler would look like (and I am not telling!)
From personal experiences, made to measures have not worked out and been a worse fit than saddles off the peg. What breed is your horse? There's plenty such as Kent and Masters and Native Pony Saddles that will do trees for different types along with being room for adjustment which is great if your horse also changes shape.
On the other hand, I do know a couple who have had made to measures and they're great so not saying it is a definate no to going down that route.
Ive had good and bad experiences. Same saddler, same horse. First saddle M2M to him as a 4 yr old and still fits as a 13 yr old, obviously been tweeked and flocked. I decided to get a new saddle as his first saddle was getting old. So got same saddler, different make of saddle and had nothing but trouble with it, so much so the saddler gave me a full refund almost 12 mths after it was fit.
The saddler said to me, if you are buying a new saddle, then you may as well have M2M as it was the same price. My horse is a difficult fit though.
