I need a graphic designer to design LinkedIn Banner Ads

I am in need of a graphic designer to design banner ads for a LinkedIn sponsored post campaign. There will need to be 4 variations of the ad with different wording and images used. I will share with you the content as well as the text to be used in the ad, the GD will need to design the different variations of the sponsored ads and provide the files in the appropriate size for LinkedIn sponsored ads. We will only consider people with a portfolio of similar work.
