Perris is awesome for beginners with the free organizing. You will find people at Perris still pay for coaching when you get into 4 way, free flying or wingsuiting. You can also improve a lot in the tunnel with a coach. The basics of turning points in the tunnel is the same as in the sky. Freefly is also good to learn in the tunnel where you can focus and refine skills really quick compared to flailing around in the sky. Generally, if you are stable in the tunnel doing static head down/up you likely won't be back sliding in the sky(if you are solo its still good to set up perpendicular to jump run though).
Once you get the basics, europe has a lot of cool skills camps that take all skill levels. You will be in small groups where you can get feedback every jump as a group or some one on ones. Tora Tora puts on a few of these, there is angleweek lite for less experienced angle flying, and probably others.
At your level, just keep jumping and get advice when you can or ask for feedback. As you start to gain experience and want to branch out into something like angles its best to pay for coaching. You get the one on one attention and learn it properly. Skydiving is an expensive sport and if you want to be good then coaching becomes one of those expenses.
