Outdoor Informational Poster Installation

I need a reliable helper to visit several outdoor locations and install a batch of A4 informational posters for me. The sites are easily accessible street-level notice areas, but I want the posters fixed neatly, at a consistent height, and weather-proofed so they stay put for at least two weeks...
