Most people do not know or understand the difference between the two. BIG difference!
DATING SERVICES: Sell you a package of dates (ala dating service). Or they promise a certain number of dates during your contract, which is usually a limited timed contract.
MATCHMAKERS: Really should offer an open-ended contract as you never know when the right person will present themselves in the service. They ONLY match you with the most appropriate people who fit your criteria and you fit theirs. They SHOULD share profiles AND pictures of your prospects with you. Their goal is not to inundate you with matches, but to zero in on the best prospects to help assure success on both sides.
