With regards to being a self-sufficient artist, I want to share a resource that I find invaluable: Lynda.com
For as low as $27/month you can access a plethora of training videos on Recording, Mixing, Mastering, and the full suite of Adobe tools (Photoshop, Illustrator, Premiere, etc). I HIGHLY recommend this.
On that same note, you can get a subscription to all the Adobe products installed on two computers for $50/month through Adobe’s Creative Cloud. This includes FULL versions of all the most powerful tools that Adobe makes: Photoshop, Illustrator, Premiere, After Effects, etc. This combined with Lynda.com for a total of $77/month is an EXCELLENT investment if you use it wisely.
