I have 2 years and a half of experience working everyday with excel and powerpoint for Ipsos, a multinational market research company doing reports and presentations for international clients (Abinveb, Nestlé).
I don't have the specifications of the proyect but I think I can get the job done quick and in the therms that you'll request. I have full availability.
