Wedding Invitation Designs, Save the Date etc

Information for the business: A book themed wedding at a zoo
Design details: Hi

We are having a wedding and the wedding venue is at a zoo. We are both huge book lovers and the actual ceremony will be held in a library room. We are having a vintage feel with afternoon tea etc and I am trying to find save the date, invitation, RSVP etc that somehow combine all of the above in a tasteful way. I don't want cartoons. I do like the idea of the invite to look like a book cover, I also like save the date cards that look like a library card and I like the ones that tell a story about the couple, i.e Ryan and Nicola met at Centurion House when Nicola interviewed Ryan for a job, their first kiss: in a bus stop on the way to a train station, they've been together for 5 years. I will attach some links to the ones I like but somehow want to incorporate animals into the design and maybe teapots and cakes. I know it's a lot to ask! Finally, I would like to be able to edit the wording on the design so that I can use it for the thank you cards, evening invitation, menu, etc. Also need to be able to print at different sizes please, probably A5 or A6. Thank you
