I’m amazed at how many new places have sprung up willing to develop your film.  This is by no means exhaustive but just the ones I see on Instagram or that I have personally used.

https://thedarkroom.com. I have used 

The Darkroom is my go to place - they have it down to a science.  Prepaid mailers, images back thru the web.  They have been around a very long time.  I trust them.

Treehouse Lab I just started using for developing ECN-2 film because most labs won’t deal with remjet removal.  I thought they did a good job and very attentive to the end product.  Just sent in my 2nd roll of film.
