It really depends on the situation... We have had great luck hiring designers that have never worked in adult before but marketing people are a whole different breed. Trying to teach someone all of the different marketing methods, payouts, and even just generally how to carry themselves in the industry is a huge undertaking. Unless they are a hot chick it's probably not worth it (hot chicks have a way of bringing in sales even when they have no clue). That stuff literally takes a year to really learn and utilize. In that year you could have someone making deals and bringing in lots of business and if they are any good at all they should have earned you more than whatever extra salary you are having to pay them by the end of that first year.
