Need a logo designed

I need a logo designed for my marketing agency. I already know what most of it needs to look like and simply need a designer to execute this as well as help with some other key elements like:
typography/mock ups/positioning etc. you'll need to be able to create various versions for use with social/website/signatures etc.

I need a fast turnaround 2-3 days at most. if you can do it faster even better.

Thanks
