The point is each person can often have a different perspective on how they ‘bid’ for work. Another factor is how you work within an industry if you have a really high profile. For instance if a big car manufacturer chooses you, you’re not going to get any kind of work from any other car manufacturer so you’re alienating yourself out of the rest of the market for the big players.
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.
