I did my own IS install on our work iPad and it was a *bear* to get done nicely. I did it, and no bubbles, but my dining room was full of swear words that evening. :/
When I got my own iPad, I went to Best Buy and had someone there put Ghost Armor full body install on it for me. Looks beautiful, no bubbles, and I didn't have to pull my hair out fighting the install. Also, the Ghost Armor has less "orange peel" effect than the IS, in my opinion.
I still use IS on my iPhone 4 (and apply that myself, since there isn't as much screen to deal with), but you might want to check out Ghost Armor, or see if a shop up there in Canada might be able to do the install.
