What experience do you have that is relevant to this project? what is your timeframe to complete?
I have ICDL science 2005, afterwards I made several ppt (not so much), put I am aware with the Microsoft powerpoint.
for the timeframe: you send me the details that include (Title, images, colors, number of slides,.....), then I send you next day the work, you review it and send me comments to fix.
Proposal:
I do work in three languages one of them is English, so the language will not be an obstacle for the work, also I am a hard worker.
If you accept my bid, I can start immediately.
