Yeah, you can make money. But, it is definitely BUSINESS first. Learn what it really costs and sell to profit. Be LEGAL if you plan on making money. The state, local, and fed tax people will notice if you aren't paying "your fair share".
I pay about $7 per slab for spare ribs (just rough estimating here), $1.79 for pork, $2.39-ish for brisket, etc. That's just what I noticed wandering through Sam's and GFS the last couple of days.
Learn about the business first. Have fun cooking que then decide if you want to fark up a perfectly good hobby.
