I need a vector poster/piece of artwork created

Design details: Design details: I am looking to get a new piece of artwork that I will print off as a poster. I would like the poster to be inspired by the 'King's Life' poster I have uploaded as an attachment but I would like the buildings in the poster replaced by the images of buildings I have attached to this email (Selwyn college chapel). Could the purple themed scarves bikes etc also be changed to red and gold theme (colours in picture attached) and I would also like some people drinking wine and a blonde girl holding a giant teddy bear also somewhere in the picture. Deadline rougly 5 days.
Target audience: Personal use
Ideas for the visual style: Similar sort of style - featuring life at cambridge
Preferred colors: More of a red and gold theme
Urls to draw inspiration from: https://www.bing.com/images/search?q=selwyn+college&FORM=HDRSC2
Where the design will be used: Personal use - printed as poster
