Ray,
Sales Ads will make or break the magazine. I know because back in the mid 80's a friend of mine and I started our own magazine,hired writers and photographers, ran it for 6 mos. hired a distributor and the whole ball of wax. Our advertising sales slumped, poor clients, wouldn't pay and we folded up. I am a graphic designer, avid fisherman, rod builder/taxidermist/artist like you, and really wanted this to work for us. You must work diligently to get the sponsors and get alot of them. No bartering or free ads. Also choose a good printer, ask to see their work, and work on them for a good price. You must have editions ready 3 mos in advance. If you want any more advice, email me.
