As a seller you can do it all yourself in some countries (not sure about US). You don't need license or training, you just have to manage your time properly and book viewings after work hours. At least from my very limited experience, the only aspect that's worth paying for are nice pictures for the ads, if you can't do it yourself. The rest is posting on real estate aggregators which at least in Europe are very popular, mostly free, and for sure not 3%. Paying a percentage of the sale for what is effectively an assistant type work isn't something I recommend.
