Multiple selection

I need your help!

I'm doing the checkout process for a translation service company.

The user originally has one English document that he wants to translate into two (or more different languages). However, he is price sensitive, so he wants to choose the different translation quality for each language.

I came up with this solution:

However, I'm not a big fan of sliders since they require quite some mental work from the user.

Do you guys have any idea how I could make this selection more straight-forward?

Any idea is welcomed!
