Rate Card Suggestion Needed

[tachyon]

Hi There,
To all the pro, I have been asked about rate card for my photography service. Since I'm not a full-time pro, I need some recommends just to get some ideas such as how much for an emerging photographer, how do I present it. I know that the rate are different by many factors including currencies and costs of living.

Or should I just ask how much did you charge for your first commission?
Thx alot
