For the time being we're thinking of ourselves as just a platform for drivers to meet users and don't plan directly hiring drivers. Kind of like a moving dating website. We would like to eventually verify the drivers insurance/licensing and award them badges on the site so users know who they're hiring, though!
Thats right you would be the 3PL and you would be dealing with 1PL(consignee) and 2PL(carrier). So likely dealing with 3PL regulation. You probably already have to worry about licensing, and insurance.
This isn't a bad market to get into. You should educate yourself though more in it.
