What's the banner size?

I have few queries
Can you please let me know where the banner will be used? How many banners do you need? Thanks

The Banner ads will be used through Google Adwords Display advertising initially and then possibly implemented through other avenues of digital marketing.  I would like one example to approve first that is 300x250.

Thanks for the reply. I will work on concept. For 11-12 banners it would be great if the budget is increased to $160. I think similar projects here have this budget.

Can you provide 1 for the current retainer and then once approved, we can up the budget as needed to facilitate the rest?  We are happy to pay for the designs.  Thanks.
