One or the other?

Here's the deal: The I and M are the first two letters of the first word of a company I'm doing the logo for. That word is IMAGINE. Anyway, the client has built an "I'm ____" phrase into the two-word logo using the IM from IMagine and the first four letters of the next word. However, I don't want it to look grammatically incorrect, hence I'm trying to sneak an apostrophe into the M. Does it work for you? Do you have a preference between left or right? Also, do you think I should make the apostrophe a different color (perhaps a lighter shade of that blue) just to reinforce it more? Thanks!
