Okay it sounds like you have very little knowledge of horses in general so I'm going to tell you to pass on a foal, as CUTE as they are, they are not a SAFE STARTER for a inexperienced person.
Someone is going to get hurt and the foal is going to end up in the kill pen without the proper training.
Even if you sent this foal out for the training, you would also have training with it inorder to continue the training relationship.
Also, as for the adoption fee on this little one is a (WAY) little out of line. I understand the money goes back into the facility to save others but this rescue is NUTS!
Here is a link to a rescue with more reasonable fee's, I know that this one is too far but do your homework for rescues, I'm sure you will come across the right one. http://www.shilohlasvegas.com
Sorry if this comes across as harsh, but I tell it as I read it and straight forward. (sometimes like a brick but the brick is harmless! LOL)
Think wisely and safely for ALL!
