Easy way to expand a site for one time fee

So I've come to find out that alot of people find it profitable to get their site translated to another language and post it up in other countries because alot of the time you can find one that hasn't been over saturated yet. The people i've talked to liked it because it was a one time fee and all they had to do was copy paste the translation directly into their code. I'm sure there are more ways to do it but it makes it so you already have a format, and a sales pitch ready to go and you get to have twice the chances of getting traffic. Any thoughts?
