We need an Illustrator to help on an Cover Art

I am a Professor at a Medical School and our most recent research has been accepted by a top journal and we got a chance to propose a Cover Art. I have an idea in my mind how it largely looks like but me or my research team do not have the expertise to make this cover art by Illustrator. The basic idea involves two components: a background with many bacterial organisms (this can be drawing or can build on a microscopy image), at the foreground, there is a magnifying glass in which we show some DNA sequences to illustrate our key discovery. It is of course open to discussion, both the design and the budget.
