I need a draft infographic colour poster design for telling a sales story in pictures

We are a social enterprise and we sell portable solar lights to people in villages in poor African country.
We need some posters near the cashout in chain small rural shops, to sell the our products being stocked for a limited period.

We envisage each poster will have a simple sales message told in pictures ( to overcome many languages & levels of education)
Simple huts on fire - cross-out next to happy family with smiling faces beneath a bright solar light (evening), & fallen candle fire, etc
Or pile of discarded torch-batteries alongside free-light from the sun drawing. (SEE DRAFT TEXT ATTACHED)

The successful PPH designer will receive more poster type-work and an opportunity to pitch for a short animated infographic series of videos. ( Note: we are in the market to supply 30-40 small audio-visual players or iPad type units to promote our sales themes cost-effectively and economically as part of our Phase 2 Promotion Plan)

Poster designs above required in 1-2 weeks. Phase 2 Audio/visual concept 3-4 weeks.
