I need social media templates to drop photos and content into

Hello!
I have an online business and would like to start sharing testimonials/reviews, inspiring quotes and some other things on my social media and would like to have some templates I can drop content into. I would like the templates to be user-friendly across Instagram, Facebook and Pinterest.

My website is nuvonova.com so you can understand my aesthetic, it is whimsical and feminine...all my social media channels are on the website so you can further understand my style.

I am looking to receive the following, but not limited to (happy to hear of your ideas also):

- template to showcase reviews/testimonials (my business is both service and product based so the template should be suitable for me to place a product image i.e a photo of a dress I sold alongside the review left.... as well as text-only testomonials.

- template for quotes i.e. my business is around sustainability so would like to share inspiring quotes from other people

- I upcycle clothing so would like a beautiful way to present 'before' and 'after' on one image.

- In addition, I like to show step-by-step process of some of my upcycled pieces and would like to present this in a much better way than I currently do (just a standard grid design)

- template with text overlay for tutorials/how to's

- template for 'new blog post' or something along the lines of that

There is also potential for continuous work so will only select those who I feel have really understood my brief and aesthetic and have attached examples of relevant work.

My current budget is £25 so please mention what I can receive for this price - and please state separately how much extra it would be to receive more.

Thanks!
Clara
