Slide design for a conference

Need the work from January to April.

We will have 20-35 slide presentations from different speakers
Each presentation will need some design work, and this specifically will be to design the more complex ideas/tables/visuals. You may need to find images for slides, and these will need to be from license-free low cost or zero cost sources.

Candidates must have specific experience of working on other people's business slide presentation(s) and turning them into a much better presentation.

You will only work with one person, who deals with all the speakers, and the project will require you to turn around designs rapidly (24-48hrs), and to ask for more info/approval of intermediate stage of design if you are not sure.

You will receive an amount per hour and a bonus at the end if it is excellent work.

The price needs to be lower than £6 per hour (minimum possible to state here).
