What kind of evidence would you like to see to know that I have established relationships with editors or can even get the job done?
Are you a UK resident perhaps? Next time you step on a British Airways flight have a look at the book they hand out to the children - I wrote that. They've printed a million copies for distribution on every international flight BA makes.
If you come to Australia and fly Qantas you'll also get a book for the children that I wrote. We're a bit smaller than the EU so that one is only 300,000 copies per year.
You could do a bit of web-searching and you'll find my name as author and editor on quite a few books also.
Apart from that, I'm not sure what else you would like to see. I haven't taken on any writers yet because I haven't found a submission that I like. Through On The Wall (an agency focussed on illustrators and licensed properties
www.onthewall.com.au) I represent two illustrators, if that carries any weight at all.
Most of the times I suppose it comes down to a conversation and how you feel about me from what you read on the website (and on my various websites, twitter, etc). As there is no formal training or accreditation process for agents, most of them are somewhat like me. Former editors who changed careers. Former freelance writers looking to expand their service offerings.
The core of my decision to start agent work was based around two factors:
1) I've worked with a lot of agents and honestly, the job of being an agent isn't that difficult;
2) I was giving out free advice on contracts, who to contact, how to pitch, editing concept documents, referring work to writers, editors, illustrators and graphic designers, getting my freelance friends work ... and all for free. I referred a $10,000 job to a fellow writer and only later on realised that I should have charged a commission.
As for being far away ... I'm a Melbourne writer who got his work on British Airways and Jet Airways (India). Is that a long enough reach?
cheers,
Mat
