a small help!

Hi friends!
I want to ask you all something.i do embroidery and someone has asked me to do embroidery on her suit, the work will be done in the front i.e poora bhara hua work-small flowers and leaves and stems, with satin stitch,

Now the question is - how much should I charge her, for I've not done this thing in a professional way and u all know how time consuming it is. So pl. if anyone of u have any idea about the prices i should tell her,pl. do help me by telling me about it..
and the price should include the material as well,


waiting eagerly for ur replies.

thanks
