Contracting - notice periods

[psanger]

I work in IT and I'm currently permanently employed and on a four week notice period. I've just been offered a contract role and day rate is very good.
The contract which I've been given has an immediate notice period from them to me, and 30 days notice from me to them.

How common is it in the world of contracting to be offered a contract with such a notice period? I'm naturally concerned that I could go to the trouble of setting up my own company, taking out professional indemnity insurance, etc. only to turn up on the first day and be given notice instantaneously, which would leave me in a far worse position than I am in currently.

Thanks
