Several new cannabis website banners with different sizes

Hello. I need several banners created to advertise my Cannabis website that I am launching. The website will be similar to Twitter or Facebook. You can see the website at Stoners.org.

Here are the sizes that I would prefer.

Leaderboard: 728x90px
Medium Rectangle: 300x250px
Half Page: 300x600px
Smartphone Static Wide: 320x50px
Wide Skyscraper: 160x600px
Billboard: 970x250px
Super Leaderboard: 970x90px

Thanks
