Very common for "normal brake shops" to tell you non-smooth surface (slotted or drilled ) rotors can't be re-trued, but it's not true.
Call around to speciality or true speed performance shops, they should know someone that can do it.
Also, it never hurts to contact the original manufacturer (or the company that sold you the rotors) and ask them.
