Banner Design

I need 1 (20 feet Wide by 4 feet tall basic poster) and then i need 1 (16 feet Wide by 4 feet tall poster). Posters can be made into several segments of 4ft by 4ft. I will be mounting these posters on a wall, i have the picture of the poster content and layout I want. The bottom 1 feet graphics are already designed in that 4 feet tall poster that will be provided by me.

Attached is the type of look i want on the poster with the same effects. Pictures will be provided but wont be of that high resolutions probably 72dpi.

Serious bidders with a portfolio only.

Thanks
