Recs for Guided Tour

Any recommendations for a guided single day tour to hit all the classic tourist spots in Rome? Going with my mom in July and we have a full day open and don’t want to worry about figuring out crowds, reservation and travel.

Also is $250-350 a person expected for these day tours? We can’t tell if we’re just looking at overpriced sites or if that’s basically as good as it gets. I will also very happily take budget friendly hotel recs. Thank you in advance!
