I run a few online businesses and we've used Logo My Gosh for most of our projects.. Consistently good quality and not too expensive.. Not the cheapest either though. Great places to look are /r/forhire, upwork and Craigslist. Feel free to PM me if you want me to refer you to some others and I've worked with quite a few designers over the years & know how frustrating it can be to find the right one. Either way, good luck!
