On going social media images

We need a designer that can work with us on providing graphics to work with our social media clients. We produce the content but need someone to create the graphics based on brand guidelines. We can provide images and logos but need you to provide us with the graphics which will be used on the various social platforms. It would be around 12-16 posts a month and would be for various client in various industries.

If you can show me some of the graphics you've done for this type of work that would be great. This would be ongoing work.

If you can let me know what budget you'd need for this work as well that would be great so we can build this into our budgets here.
