Get to a magazine store and grab a copy of The Backwoodsman. Pretty sure it's the current copy that has a long article on tanning, that shoots down some of the 'common wisdom' and points out the facts O life, that tanning and doing a decent job of it yourself, is a bunch of physical labour.
If you don't want to risk ruining it, run it through a commercial tannery.
Dunno what all is available in your area, but Halford Hide out here does a good job, for not much (around $300 IIRC, check their catalogue) money. OK. $300 is fair money, but if you want to do it, it's gonna be a bunch of work!
If you cannot find the article, check their website for back issues.
It's good read. The guy has an aversion for brains mush, and still gets good results.
Cheers
