Getting a bow refinished usually runs around a hundred bucks. Filling in holes, removing twist and such would probably add considerably to the cost. That's the bad news. Good news is that reconditioning an old bow is a great do-it-yourself project. All you'd need is a selection of drills to open up the holes for some wood plugs, some good wood glue like Titebond II for gluing the plugs in the holes, maybe a 4-in-1 wood rasp and small rattail file, various grits of sandpaper, stain to match the color of the plugs to the bow wood, and a can of spray polyurethane. And, naturally, the time to do it.

You can fix the twisted limb real easy by running hot tap water over the limb to heat it up and twisting it the opposite way until it stays straight. Some people cringe when they hear someone recommend the water treatment, saying water can get into the wood and ruin the bow. They prefer using a heat gun to warm up the limb. Frankly, using a heat gun worries me because, if you're not careful, you can get the limb too hot and cause the limb to delaminate. As long as the wood is well sealed, water won't soak into the wood, so only do that part after you've got the bow refinished.
