Some concrete contractors, most general contractors do this - but pricey to use them. I think typically basement waterproofing contractors and handymen probably do the most of them.

Not rocket science - just have to be sure to talk to them about how they are fastening to the wall (so as to not form leaks into the wall through boltholes - a VERY common problem, especially with hollow block wall and structural brick which has holes in it for rebar), how it is going to be sealed to the wall, whether you are doing drywell/gravel bed in the bottom for drainage or concrete infill with mastic perimeter seal (in areas with periodic high water table), and how covers are going to be sealed to the wall and well to keep out water/insects/frogs/mice.

You should also discuss grading around the well so water does not sit up against it, and provisions for easy removal if needs to be bailed/cleaned ever - fasteners on cover should anticipate easy removal in the future.

And don't forget fill around well needs to be well compacted to ensure water running off the cover drains away from the well, rather than soaking into the backfill aroundthe well and causing a bathtub effect right around the well, which can lead to basement leakage issues. I can't begin to count how many basement leaks I traced back to window well backfill becoming basically a sink for all the water falling in the area or running off the roof.

Also consider moisture removal from the well, because with dampish dirt or concrete in the well you will get a lot of condensation and fogging of the cover in the well. Can be mitigated by rain-shielded ventilation points (screened) high up on well against house, by concrete sealer, or in drywell installations 4-6 inches of crushed coarse rock in the well to prevent wicking from below up into the well.
