Creating artwork for printing

I need to produce two posters in different sizes for advertising on backlit film for billboard Posters. I have a sketch of the design concept needed. I need to turn this skecth into a vibrant artwork of 1:1 scale for the following sizes - Poster size: 3.87x1.82metres finished artwork to be named as Trakie The sketch shows the full content that will make me happy if they can be incorporated. The pictures are for illustration and may not be the one used. Everyt other logo is required in the finished artwork. The fonts and colours of the text will need to be big and generally have bigger impact on the finished product. This is needed for a quick turnaround. psb , ai , esp formats to be produced on a 1:1 scale I need a pricing for this and more importantly duration for the work.
