Help me write up an email to my coworker, Sheryl, informing them that I'd love their help planning a surprise birthday party for our boss, Mr. Jonathan. I want at least three sentences of the email starting with an I. Sign it off with my name, Bob.

Subject: Mr. Jonathan's birthday
Hello Sheryl,
I hope you've been well. Just a quick one. Mr. Jonathan's birthday is coming up, and I'm responsible for planning it.
I have a lot of ideas, and I wanted your input in planning a successful one. Specifically, I'd love to discuss choices with regard to the cake, the decorations, and the location.
If your schedule allows, inform me of your availability. 
I hope to hear from your soon.
Best regards,
Bob.
