I think a lot of it could be made simpler by a course near 'developing' or 'to-be-developed' systems. If the construction company (or whatever) shows up and offers the locals a deal like, "we'll build the stellar-laser systems you need to launch and decelerate shipping from all over the galaxy, and get you on the beamrider network, in exchange for these three tiny, rocky dwarf planets way the hell out in your Oort cloud," I think there'd be a lot of takers.
Key is getting to places before they're significantly developed. If you're in a system where they've already found important uses for those ice dwarfs, and already built their stellaser and beamrider network stations, the bargain is less compelling, and then you're just buying a few loads of materials on the open market.
In fact, if located on a lonely but auspicious route, the construction company might be in the business of developing that infrastructure in entirely undeveloped systems and then selling the value-added systems to colonists. Among other things, it would build a long line of new frontiers VERY STRONGLY CONNECTED via beamrider network - sure to attract all kinds of traffic and trade year after year over the next few millennia, and how awesome is that?
