Placing an Advert

Hey Y'all!

I was wondering if I put an advertisement on my videos, what would you guys think? Also, if you wanted me to place your advertisement on the video, what would you give me in return? I will probably make a demo video of what it would look like. Anyway, please leave your thoughts.

PS. Search J2mpm3n on youtube. The user has made some cool claymations that I thought I should point out.
