I used to work several year in Kazakhstan and got my police certificate for international use via Kazakh Service Centre. I think - this is the only company that charges real money and does the work within 10 days. Before, I had a bad experience and order the certificate from another KZ Micki Mouse company, send them money ( 200 US) via Western Union and never got my document. I was mad :-(, so found Kazakh Service Centre, paid them 350 US via PayPal ( credit card) - and got the proper certificate in 12 days. Kazakh Service Centre provided all paperwork, so the process was smooth...(kazakhservicecentre.com/police_certificates.php)...They actually did apostille for me as well on this document.
Good luck!
