When you enter, you also have to give some basic statistics that will help your bowyer know what can and can't be done. For example, I would state that I have a 26" draw, can't handle much over 50 lbs of draw weight, am right handed, and can shoot with or without a shelf.
Once my bowyer has my information, he or she can flat out do anything they feel like subjecting you to. They can make an 80" longbow or a 38" sinew backed Dall sheep shoshone style bow. The bowyer might research everything you have posted to get a fix on what style bows you seem to like and they may use that for a template....or they might decide you need to be pushed out of your comfort zone with another style of bow. All the while you are doing the same for someone else.
And then one day, you are wearing camoflauge and facepaint, squatting in a bush, not moving a muscle...not even blinking as a fly walks across your eyeball when the mail truck drives up. The driver steps out with a long skinny package and you launch, screaming, from the hide-out! You snatch the package from the postman's hands and run pell-mell up the drive to your house while chewing thru the 48 layers of packing tape holding it closed. Strings of tape tangle your teeth as you mutter to yourself, "My precious! Precious! Oh, my precious!"
That's pretty much it in a nutshell, right folks?
