There are some bow tuning seminars that you can pay for, to teach you the basics. I think PSE runs one. Certainly, you can learn a lot on your own if you buy lots of books on tuning and read everything you can that is available on the internet. Use the search function thoroughly on archery forums to learn as much as you can on a subject. Just be aware that you have to carefully read to discern who is knowledable and who to ignore.

There are ususlly lots of local people who will help small businesses with the general knowledge needed to run a small business. Make some phone calls to your local chamber of commerce and other local small business associations.

My only real advise is to forget about the partnership - they don't work and I mean almost never. For every one that gets by, barely - there are 100 that fail and usually very quickley. No two people have the sames goals and ideas on how things should be run (among a thousand other things you'll disagree on). If you do a partnership, you'll be severely handicapped from the beginning. I can't stress this more. I've seen some last several years, but they all eventually fail and in every single instance the people getting out, wish they had never done it. Don't do it because the other person has money or a building or anything that money can buy. You can hire part-time help a lot cheaper than a partner and you'll pay them less and get to run things your way.
