You don't have to pay commissions, you can hire a flat-fee broker. As far as offering a finder's fee (buyer-broker commission), well, you can do away with that, too. Although it may keep you from being entered into the MLS.
As far as "you get what you pay for," I prefer to say, you can only hope to get what you pay for; if you pay little, you hope to get that much, and if you pay a lot, then you hope to get that much more.
In my experience, people prefer to work for more money when they can, and settle for less when they can't. I wouldn't want to suggest that my discount-priced colleagues cannot provide the level of service as a full-priced colleague . . . but, why would they charge less if they didn't have to? Out of the goodness of their hearts? Because they don't like putting money away at the end of the month? Because they're independently wealthy and don't need to earn money?
All the best,
