Social media post

Hello, I am looking for someone to create promotional pictures for my Twitter account. I have guidelines in place that the content must follow, which I'm happy to provide. The content should be engaging and eye catching, with clear messaging. The promotional posts must be focused on one call to action, or message. I expect that each post will be carefully reviewed and approved by me, prior to being posted on Twitter.
I'm looking for someone who is experienced in creating social media content, and is able to quickly and efficiently create professional and original posts. If you feel that you have the knowledge and skills to accomplish this task, I would love to hear from you. Thank you.
