re: real estate license/side job

What's your end goal? Are you really familiar with the land around you? Are you well connected and have a robust social network? These are the first things I would think of.

A new agent has to work under a brokerage. Absolute horse shite system, but you can't just get a license and start winging out deals as they come up. That brokerage may or may not have any specific requirements for work, but you can decide based on that.

Not to be the "it's too late to start" person but I'd assume that there are already some well established people in your area and even at whatever hypothetical brokerage you end up at that you'd have to try to displace. That goes back to your knowledge of the area and your social network. If yes to both of those, then you at least have a leg up.

If you're talking about dealing with large tracts of land then presumably you're looking at a bunch of inquiries and long deal cycles with a lot of negotiation and possibly several trips out to the land that often might end in no deal.

I think the real estate licensing is easy, and I think you can find a brokerage that will take on people, it would just come down to 1 do you want to commit the weeks to learning and taking the licensing exam and 2 do you want to start engaging in the sales process on that land.
