LOI from Kazakistan

I am planning to visit Kazakhstan from 25th to 29th as tourist, I
think I need LOI for that, how you can help me on that. If some one can really arrange LOI, I can pay her/him for that.

Currently I am in Uzbekistan from last 3 years, holding Pakistani Passport.

I'll be visiting with my family, Kid and wife, they don't require VISA to Kazakhstan.
