Singapore Expats

I've just came down to Singapore to work( as a photographer)...but i hv degree in accountancy and also want to get some experience by qualification while i'm here (along with my first work)...so i was offered to work part-time for one economic research company (3 hours a day - 2times a week)...my task is just to collect some data n orginize it in proper way..What's the average pay for it (? They offered 20 SGD per hour ... .PLs consider that i hv no experience in this field n work is very simple..My first job is quiet well-paid so i need just experience....but still dunt want to be too underpaid!!!

Yr advice is much appreciated

Thank you
