Social media graphics/designs

Hi all,

Real simple one here. I'm in need of banner designs as well as some colourful variations of our logo for our social media.

I'm in need of one for : Facebook, Twitter, Instagram and YouTube. Variations of the same design in different colours for each platform would be ideal, so they're not all the same.

I have the logo as a psd file and there are no existing ideas for the banners. But I want something simple, striking and effective. We're a digital publication and content site (https://subscript.it), currently going through a re-brand.

Any bids without work examples will be rejected and please do not attempt to contact me outside of PPH.

Thanks :)
