Why not see if Mike is open to a licensing deal, where he gives you the right to reproduce his exact recipes using his brand, and he gets a % of sales? That way, the product will be exactly the same. Then you won't have to spend countless hours trying to duplicate the product, and Mike gets to benefit from your investment and efforts. That's a win-win all the way around.
That said, I'd LOVE to have Secret Weapon available again, and same for Competition Beef & Pork. I still have a little of both left, and am dreading the day I'm out.
PM me if you'd like to discuss further - I'm a marketing consultant, former president of an ad agency, and have put together a lot of revenue sharing deals & contracts.
