Poster campaign for special offer

I require the Following Artwork for 3 banners all banners will be for display outside a petrol station and will be for people driving past to see. Banner size will be 181.7cm long by 76.2 cm high Sticker 27 x 38 cm to go on the side of a coffee machine to promote the offer. A4 poster for displaying on counter and shop door I will provide a picture of the location the banners will be displayed in to give an idea coffee machine etc. The promotion we are offering is giving everyone who wants one a free cup of tea of coffee to take away. There are no catches they don?t even need to be a customer. I would like all the items to have the same theme and coloring I require up to 5 different concepts if we get it right first time then only one would be required. But I need some inspiration.
