Like Primestar31 suggests, C-band hobbyists systems are usually installed and maintained by hobbyists. If KU, check with local ethnic communities or Craigslist for technicians. Usually charge one to two hundred dollars to aim a fixed 90cm dish. Higher for a motorized (if they will even do it).
Many C-band commercial installers are available through booking agencies. The cost is high and often billing for travel time, contracted blue collar crew, concrete delivery, rebar, poles, distribution wiring, grounding, etc. Not unusual for a commercial installer to invoice several thousand dollars to install your prepurchased or used dish. Often a higher invoice if the system is partially assembled (right or wrong) or clean-up / disassembly is required before starting their nstall.
They will likely not be interested in assisting with the hobbyists receivers, controllers, etc. Typically, will provide assembly, installation, tracking the dish on the arc using their test equipment; then hand the keys to you to integrate with your gear.
