I'd like to have some advice on resources for beginner freelancers. I have just made my first contract and am in relation with another client which will hopefully mean another contract and I am kind of lost as to how do I organize all of this.

I know how to take care of projects and how to develop stuff efficiently and talk to the clients, that's what I already do at my day job, but everything about managing your own freelance work and turning it into a business is unclear to me.

I have watched two great videos that helped me set a few rules to not get screwed over by clients but I would like some resources. Examples include : downloadable contracts or terms of use templates, advices on how to manage client's money, how long should I give the client before telling him his payment is late, which fees should I charge, etc..

The two videos in question : Fuck you, pay me by Mike Monteiro http://vimeo.com/22053820 and Going Solo http://vimeo.com/21475881

Thanks in advance.
