Rickwalleye, Since you are over budget already one thing is for sure harvested bears need special care as apposed to a deer. First off the hide goes south faster than the meat. If I were you waited years for a tag and I harvested a bear this is what I would do, and average it out over the 6-10 years it takes to get a tag: Bait, Hunt, Processing, and Mount are what $125.00 per year?
Retrieve and field dress ASAP unless temps in the low 20's will take a bear pelt and meat south in no time. Don't blame the taxi, or processor if the hair falls out, or the sausage tastes like crap, bear meat needs special care.
Find someone with a walk-in cooler to hang your bear for the first 24-72 hours to store your bear, and take it there ASAP. This is better than any ice blocks, or anything you can do on your own. Good air circulation cools down the hide and carcass and protects you from the obvious pitfalls with Black Bears in WI. Most registration stations charge little or nothing, $2.00-$5.00 a day and this will go a long way to preserving your pelt, and cooling the meat to a temperature suitable for butchering. The Heavy fat cuts much better when it is chilled to the right temperature so butchering yourself is easy. Most Taxi's will skin for best measurements and quarter for a small fee, money well spent.
Finally if you have blown your wad before the hunt I might suggest that you wait another year, the difference between a poor hunt and disappointing mount is waiting for enough $$ to do it right. Skimp and you will be disappointed. Take it from one who knows.
