After claiming the system and setting up the beacon, you choose what primary station you want to build. That determines the effort required. Options vary, if you want to build a starport (with Coriolis being the easiest), the fee is hauling about 55-70k of goods within four weeks for the initial starport (as I get it, there is no time limit for building subsequent ones), and I would recommend a specialized Cutter for it, it's a whole lot of stuff. Got to 60% in a top engineered Cutter, solo, in about a week, playing 2-3 hours a day. Stations are way cheaper and can be done in a couple of days without too much effort, so there's an option for everyone. You decide. But definitely go and try it, it's fun!
