Step above that would be the "gig economy" marketplace style sites for generic logo creation. Be wary here though, many people spam these with knock-offs or direct copies of existing logos & resell content. Basically make sure to image search anything you get. From a pragmatic standpoint you can get something pretty good out of these for the short term before rebranding down the road.
For finding serious custom branding services you can look through a number of creative sites for talent. Creative job boards like Cloroflot (www.coroflot.com/design-jobs), Behance (www.behance.net/joblist) or Dribbble (dribbble.com/jobs) can fit the bill here. You can also search portfolios at these sites and directly reach out to designers that match your style.
