mine will be:
1. the signed contract
2. phone calls (i am NOT posting my phone number on the website as a. it's my private number and b. i hate phone calls most of the time anyway

3. don't work at weekends (i'm normally down at my brothers every weekend, he lives in somerset/devon - and yes i may promote my business down there!! - he may be my 1st client...!!!)
4. payment on invoices (10 days after date of invoice)
that's it for me for the moment...
