You should make your own .com domain and buy a server.
The domain costs like 10$ a year and a good dedicated server is about 100$ a month.
Unless you want your business to be some half-ass amateur thing.
He can buy domain with discount codes.
OP check

and his site is new i don't think he need dedicated server now, a vps will be fine.
