Union and non-union jobs have always been two separate markets. Non-union work is more visible and attractive today when compared to years ago, due to online casting. The availability of professional talent for non-union work has led to a reshaping of the voice over industry. An open market means that each professional voice actor sets their own rate based on what they need to cover.
However, there are lots of second tier voice over agencies and ones that are just getting established. One of your goals as a voice actor should be to get listed by an agency. However, wait until you have at least established yourself and put together a portfolio of work and super hot demos you can send out to them for consideration. When selecting an agent you need to carefully examine who they currently represent and then ask yourself: How do I fit in here? Does this agent have anyone like me on their books? If not, you will most definitely stand a better chance of being represented.
As editor, you need to turn the raw recording into the final version of the file you'll be sending to your client. Editing during a recording session can be problematic, and particularly so if you're recording in a domestic environment. How can you expect to hear the drone of the dishwasher ruining your recording if the dishwasher is still running as you edit? I'll look in more detail at setting up a voiceover recording studio next time, but for now, if recording in a separate room or isolated booth isn't an option, at least try to edit the file the following morning (or maybe at night) when there's less noise around — because hearing your recording with a fresh ear and in a quieter environment will help you to make better editing decisions, and will reveal noises that slipped your attention earlier.
