Best advice I ever got from a brewer, "Don't grow what you think I want or even what I think I want. Grow what your can grow best and I'll make a beer around it."
Here's what you will run into.
- Established brewers may be leery, may not give you the time of day or may just give you a pint and tell you to come back when you have something. They've all ready heard from a dozen other people how they are going to grow hops but none came back. Or worse, they bought some local hops that turned out to be crap and they are burned out on the idea.
- New brewers will be excited at the opportunity but they won't know what to tell you to grow. They will look at there pile of hops and say, "Cascade" or "CTZ"...whatever they use the most. But they are new and may not have developed their flagship beer, yet.
Step one is putting together a REALISTIC business plan. There are plenty of resources on this website, on a Facebook forum called "hop growers forum (nationwide)" and from the folks at Hops USA. Figure out what it will cost to grow, harvest, dry and process and all the infrastructure you need. Then figure out the price you need to cover your costs assuming you hit full production about year 4.
Then go to lupulinexchange.com and see what the prices are for different varieties. Understand that there is no guarantee that what is hot today will be hot tomorrow. Pick three varieties that you think will work based on the price and whatever Rutgers/local brewers advise you to try. Then pick three more that appeal to you for some reason but aren't that mainstream. Hopefully at least 3 of those 6 do well for you and you expand on those.
The key is if you find an odd variety that grows really well for you and you do a decent job of growing and processing it, the brewers will find a way to make a unique local beer out of it.
