Do you have a preferred banner dimension?

And for the final files, can you confirm that you only need ONE size banner or multiple sizes?

are you willing to buy stock photos if ever?

thanks!

Manila,
each of the banners are the same side. Please access the uploaded information to Design Crowd as there is a full description of the project and a number of files that would be helpful in answering the dimensions question and giving you a sense of what is desired.
thanks for your question.
