I need a poster created for a bus stop advertising campaign

I have recently taken over a second pet shop, and am in the process of putting together an advertising campaign. One area that was extremely effective for the previous owners was a bus shelter poster that is moved around the town weekly (i.e. there's 7 sites across the town and each week it is in a different site).

I have changed the company logo and colours to work with my existing shop details (different shop name though), so the existing design is no longer appropriate. I have attached a copy of the previous owners poster so that you can see what they did, however I would like something a little more punchy. I have also attached a copy of the new logo.

One thing that I do know is that I would like a QR code to go to our Facebook page, as that is the main thing we use (the inherited website needs changing long term).
