Where are you looking to work Shredder?
The only reasonable one around at the mo is for Silverfish in SE England.
Capn Flashheart is right – the first thing that happens when they are looking is that a director will call a few known accounts in the area and ask who their best rep is. Much easier/better to poach an existing "face" than it is to take a chance on a newbie with no trade experience. It frequently takes a new guy 12 months to gain trust with dealers whereas a known guy just needs a few days to get going.
You need a lot of luck to get a break into the trade at that level. Try an in house telesales/support role for 12 months and then try to move into the role you really want.
Having said all that, it does happen – i had no experience but knew my way round a bike, had some people skills and had a right place/right time moment with a sales director who took a risk with me.
Its the best job in the world if you can do it – loads of great characters, weirdos, challenges and fun.
