Hi pcauthorn, I would recommend to read some of paul graham's work "Do thing's that don't scale", as well as begin reading/watching some great information on entrepreneur published on yCombinator youtube channel. The best way to meet someone who has problem that needs to be solved is to get experience in that field and interact with people who are currently working in that area. For example, if you are interested in working in applications for food service, try working in bars/restaurants around your area and find out what the pain-points are for these restaurants.

In regards with meeting someone currently I am participating in yCombinator StartUpSchool program, where they allow you to meet other founders/hackers with similar skills and goals.
