Key to my application is I can write a good letter and CV/resumé, whereas most people can't. They also don't know how to research their industry: finding the right companies, working out who to address the letter to, how to followup a few months later (or by phone a week later) without sounding pushy.

So, your idea has "legs" :) Somewhere between a virtual personal assistant, a resumé-writing and mailing service, and a campaign planner for job seekers. I want royalties ;)

It's not a bad idea, but the issue is going to be to find enough people with attractive handwriting...
