Contest Quick Box Design $15

Hello I am looking for a quick box design. The box must be unique, thin. The box should be able to contain a A4 document. Inside, the box has to be divided into 3 parts. Each part with the capacity to contain a 30 pages documents, so total is 90 pages document for the 3 parts. The front of the box should have:
1- logo of our organization
2- The Name of the conference: Nduenga Conference
3- the following inscription: see mock up

The inner part should have logo and inscription (see mockup)
The back of the box should have logos of sponsors.

@kobo you have just made the mock up look nicer. I am looking for a nice design of an actual box. See the two examples attached to have a better idea. I want to writing on the front page to be written like the white box I have attached as a sample. Thanks

 

In mock up is used green, i use only that color, if you want more color, just say, i can change.
Is a simply style, as are your images, if you want, i can change.
