Choosing an engine for an aggregator site. What to choose?

Question

CMS

Dear, good night! Prompt cms for the service aggregator site.
There are two sides on the site:
1. The customer sends an application for the service to firms.
2. Registered firms that review applications and consider whether they will take the job or not.
The principle is very similar to the uremont website (Which is about the selection of a car service).
The service aggregator is planned on a very narrow topic, so the loads are not particularly expected.
Looking forward to your advice, thanks!
