Where is a good place to get commissioned artwork?

I have a gift idea for my husband that involves commissioning some specific custom artwork (Pokémon-themed, in case that matters!). I did some cursory searches and turned up results on Etsy and Fiverr, but some of these look like they’re automated and are suspiciously inexpensive. Other offers on those sites look more promising, but I’m not even sure if Etsy/Fiverr are where I should even look in the first place.

I’m happy to pay an artist for their work and want this to be something of quality. I’m also fine with waiting on it — some of the stuff I’ve found so far looks tailored for speed.

What’s the best place I should look with quality artists who I can pay fairly for their work?
