I don’t get why it’s not common for people to cut out the middleman with these services that just connect a provider with a seeker. Then the seekers can stick with a reliable provider when they find one and the provider can take the full amount rather than giving away a cut (or, more accurately, accepting whatever the middleman thinks is the least they can give without driving the provider away). By the time they come in contact, the middleman has already added all of the value they can to that interaction.
