Willis and Co. I have heard from a friend have had a bit of reputation for being a hard selling firm which specialise in small caps. Alot of these firms change their management so often they can sweep all the wrong doings on the past management of the firm and be safe in the knowledge that there wrong doings will not be punished untill they have earned ridiculous amounts of money. Although you might earn alot of money doing this, I think if you have any kind of ulturistic feelings then you will find it a very difficult jobs to do for more than 1-2 years.
Plus alot of these kind of broker's actively seek a certain type of person to do this jobs. They dont want a classics graduate from oxbridge, all they want is someone who can take rejection after rejetion and doesn't have anny qualms with ramming shares and stocks down people's throats. Most of the people in these places are kids from essex who left school with 2-3 A levels, who's only ambition is too earn as much money as possible whatever the cost to some old ******'s pension.
