UK BASED Graphic design wanted for social media graphics + power point presentation.

Hi, I am from Strive Supply Chain Ltd & we need a fantastic, commercially focused UK based designer to do the following.
I can't stress enough that we need a proven designer who has a lot of experience in B2B design across social media platforms.
1] produce a powerpoint presentation [approx 20 pages. All content will be supplied in order & on a word document.
2] redesign our social media template. We uses c5 variations of the same design across linkedin, twitter etc. It's OK but can be a lot better. We need the format to be editable at this end - which we currently do via adobe]
3] design a simple 4 page PDF brochure. This will be based on the final image used on the templates, all content on word doc.

Many thanks.
