If anyone should tell you he or she can help you out, you have to be careful about the person because he or she is trying to scam you..the best way you can go about it is to go down to passport headquarter in Abuja because I did my own yesterday..the cost depend on who attend to you,but for me I spent 95k....60k to government account 30k for the officer coleleting your documents and 5k for officer taking your passport
