A Man. A Van. A Surprising Business Plan.
Quite an interesting story, I would like to point out that being from Pakistan, I have seen such services since the first day that I went outside a passport office. 
Here in Karachi, you can find people providing Copy services, to scanning and printing and also what they call here is document composition where the guy writes a complete letter application for the client to be submitted in the Govt office. You can also find different Oath Commissioners (for document attestation). And all these are commonly found outside courts and other Govt offices, usually having a desk under a tree !
