Fortunately, the internet has made this easier and more open. Most businesses have a logo, brand and a website. This forms the basis of how people get to know them. As a voice-over business you need to recognise that you need to market yourself. This involves ensuring you get your brand, your business, in front of the right people. Marketing though is also about building relationships with customers, not just selling to them. The more customers that use you on a regular basis the more money you can earn and the easier it becomes to achieve a good income.
First, I like to listen to the entire voice over recording from start to finish. I may make notes here and there to remind myself of something I want to go back and edit, but this time through I really just want to concentrate on the overall pacing and tone of the recording. Does it sound like I hoped? Did I rush or speak too slowly? Did I flub any words, mumble, or misspeak? Are there weird silences or unknown sounds?
While having a broad set of voice skills is beneficial, many voice overs establish themselves in commercials and more general corporate voiceover work before specialising. Having a niche or specialist focus though can make a difference in earning potential. So, bearing in mind the question: how much money do a voice actors make, will also depend on the level and experience in a given niche e.g. animation, audiobooks or gaming.
Also listen for sibilance. Strong 'ess' sounds are best corrected at source, by using good mic technique, but sometimes they're unavoidable. If you hear an 'ess' that really sizzles in your recording, you can manually reduce its volume. You can, of course, also use a de‑esser, but do be careful, as applying some de‑essers to the entire audio file can alter the sound of your recording. It often works best to apply them to short sections, either offline or using automation. My preferred de‑esser plug‑in is the one sold by Eiosis (www.eiosis.com),Make sure you record some silence at the end of each take. That way, if a great performance suffers from noise issues, you have something to feed your noise‑reduction processors. Just don't rely on this technique too much! which cleverly separates the esses from the rest of the audio and allows you to manipulate them independently. If you want to learn about some more advanced strategies for de‑essing check out Mike Senior's article from SOS May 2009 (/sos/may09/articles/deessing.htm).
At the end of the day, we all need to have a baseline of what is an acceptable pay rate and what you may need to walk away from politely. This is a competitive market and when you have put in the training, financial investment, technical education in perfecting your studio sound, and countless hours practicing in the booth you must advocate for yourself and know your worth!

At this point — unless you're tracking for broadcast applications (where they don't work to peak levels) — consider 'normalising' your recording to an optimal level. Normalisation can be used to push the loudest peak to around ‑1dB and increase the volume of the entire recording by the same ratio. Of course, you can also tighten up dynamic range (the difference between the softest and loudest parts of your recording) by manually reducing the loudest sections of the recording before you apply normalisation. On a final note, if you do plan to use a compressor, then you might as well add gain at that stage instead of normalising.
