I had a project requiring some voice acting so I take to Fiverr, looking through talent. Plenty of $5 jobs. But when you look at the commercial/broadcast rights, they are incredible. $90. $150. For 500 words. And while I get that there's a reason to talk about these things, tacking them on like that is akin to eBay sellers posting something for $10 then charging $100 shipping.
What else am I going to use a voice over for?
And I do have a solution. I think that if you're going to charge for Commercial or Broadcast rights, those should not be option. They should be required. So you no longer have a $5 job. You start at $155 dollars for whatever your word count is.
Because honestly, people are here to pay for a service for business related functions. And if you genuinely do NOT need it (like you're doing a training course for your internal support team) then you can negotiate a custom offer.
I honestly walked away from some brand new, first time sellers because they were tacking on incredible rates for those things.
I'd love to hear some other opinions.
