Illinois deer...25 pounds of meat would be a fawn. Typical 1.5 year or older doe will yield 35-60 pounds of meat.
If you are in the south...25 pounds of meat from a medium size doe may be about right.
IMO Learn to butcher your own animals.. Skin and quarter in the field/at camp. Put the quarters in garbage bags on ice (you do not want the meat directly sitting in ice or water). Complete the butchering at home. If you have no one to teach you to butcher watch some youtube videos...it is really not difficult.
