Artwork to be specifically drawn for a birthday card

I would like for someone to produce some art for the cover of a leaving card. It is for a much loved colleague who is leaving our team. I would like for the workplace building to be shown. The image should depict my colleague leaving the building / walking away from the building, and the rest of the team bidding her farewell from the windows/ or from just outside of the building if easier. I have facial pictures of all. Imagination will have to be used for the bodies. I have an image of the office building. The image will be printed on to a large card for people in the organisation to sign. The size of the printed image (card) will be 293 x 419mm. I don’t wish to share images at this stage but will upon discussions with artists. image should be colourful
