Hi friends

I am a newbie trying to get some clients added to my portfolio. I will be talking to some prospective clients next week. I am planning to offer my services free only charging them for the expenses like web hosting and domain name registration. I dont have any portfolio or sample websites to show them-only a brochure and postcard that I created for a friend. Have a couple of questions now.
1) They want a price quote for the expenses. Does anyone have any reference or document already done with the expense information like web hosting and domain. Are there anything else involved.
2) Do I have to make them sign any papers (My services will be free of charge)
3) Does anyone have a client website requirement document that I can re-use.
Any other information or help is highly appreciated.
TIA
