Since this is a flier, hand out of sorts. I wouldn't includ the words "if you have any questions, please call me..."

To me, that sounds like it's a person to person letter. Rather than a company to community. Which is what you want with a flier.

Here are my examples.

[email protected]
543-555-1234

Or
E-mail: [email protected]
Phone: 543-555-1234

Note that I put the dash in the e-mail. I did this so that the two would line up at the : and beginning of the contact info. Basically line up the start of the two contact information.
