Template designs for social media posts

I need a designer that can adapt our brand identity and existing assets to make a series of eye catching template posts for use on social media. Ideally the templates would be provided in Canva. We are a children's eco brand, so the design needs to reflect the fun, yet trustworthy values.

I need posts that allow us to show children's activities / crafts (photos), quotes, reviews, fun facts, company info etc...

We already have brand guidelines, fonts, colours, graphics and patterns that can be incorporated into the designs. But I am looking for someone that can make sense of this and translate it into a series of cohesive designs.
