I will also promote you as a new sponsor via a blog post, on Facebook and Twitter.
NOTE: I can help you host the banner for FREE and if you can't create it, I can also help you create it. NOT FREE., Hence you won't have to worry about bandwidth on your own server. Your ad runs on ALL Pages of the blog, including the homepage.
Should you also be interested in a paid review for your product, service or business please do contact me too.
Cheers.
