Creating images for Pinterest and uploading

I'm looking for someone to create some images for Pinterest -please. I have a website with about 200 blogs, each one with an image already on the website. I would like at least one "tall pin" image created for each blog, either using the image on the blog or a brand new image.
I would then like the images added to the Pinterest account and linked back to the blog post.
Please could you send me a quote, with a timeframe and mention any relevant experience.
Thank you,
Suzanne
