Jess Fortin at Cut to the Chase stables in Purcellville,VA is the best! I can’t recommend her enough. At the moment, she just has a lighted outdoor; however, I believe building an indoor is in the works!! 
Also, she has a variety of full/partial/consignment training options so you don’t have to ride in the dead of night during the week. It’s ideal for someone who works but maybe has an RDO or telework day so they could ride 3-4 days themselves and then she can ride whichever days you can’t make it out.
Jess is truly a top-notch horsewoman, she works harder than anyone I know, and she will accommodate most any budget. I encourage you to contact her, as she is on Facebook and via her website: https://www.c2cshowstables.com/
Also, Hedgeland equestrian center/Katie Petronelli is great and there’s an indoor. I think it’s in your price range for board, although I know with lessons/training your costs will add up to the same if not more than at C2C.
