Coffee Shop

I need an interior design for a coffee shop. The coffee shop is intended for a proto-type interior design for a coffee shop that will be selling energized coffee and other drinks ( drinks enhanced with herbal nutritional supplements ). The idea for the look & feel should be natural colors, and more of coffee plantation feel. For this pro-type, the size of the shop will be 15' x 37'. To start with, I can send a floor plan to the winning bidder. I would need at least 3 designs and color schemes to choose from. Many Thanks.
