Helimutt,
Like your attitude. Just beware of Profit hungry owners / operators. If you become so valuable because of the extra profit you generate for their pockets, you run the risk of always getting the jobs no one else wants!
Make sure the deal is struck to your terms!!
Jon Curd worked freelance with us for several seasons as a CPL(H). Great Guy. He's now a Captain with British Midlands and even harder to get hold of.
Best of luck.
