Hold a sign in Brazil ( preferably Rio)

Hello I have a project about Brazil in my university and I need someone in Brazil to hold some signs and write basic words on them to put them as a cover for each section I have in my project like Culture, Food, Tourism, Football, etc... You just have to hold papers and take a picture of it with a background that shows it's Brazil (preferably Rio), you don't have to show in the pictures at all, just your arm and the papers.
