I work perm for a company in london and I was offered a 6 month project in germany which I jumped at. The project has been extended by another 6 months but I have found out that my company cannot do my taxes after me being in germany for 6 months ( I gave up my rented flat in london and am resident in germany). They have agreed that i can change over to a contract for the role.
Can anyone recommend a good firm to handle all this for me as it's my first time contracting.

p.s what daily rate should i ask for if my perm salary is 30k, i have absolutely no idea??????

thanks
