Poster for presentation

Are you busy at the moment - a poster 6ft 4 4ft for a science project to be used a fairly significant event. I have about 10 days to get it done - but it must be finished in that time as the conference is a fixed date. An interesting project global oxygen - ocean acidification - global warming etc - I will supply text plus idea as to
backdrop images - it needs to be eye catching - arguably an important issue - probably 10 -15 hours work I would guess all told -- thanks
