Need graphic designed image for social media posts

Hello,

I am looking for someone to design and create an image to advertise a research survey calling for people to participate in a research study. In other words, it needs to be eye-catching, grab attention, give people information on the survey and research and direct them to the web link to take the survey.

I need it to be an image that can be posted to social media - primarily twitter.
Price negotiable.

More details on wording etc. will follow once project awarded.
