I need a logo for digital currency

Hi,

I need a logo for a digital currency, it should be a mix between a man and a tree, I attached an existing logo as example. I want it very minimalist (even more minimalist than the example) and monochrome.
I need 4 versions :
- The logo with the name "LIFE" police "MontSerrat" and the slogan "Life Insurance For Everyone" police "Roboto" below or aside.
- The logo with "LIFE" police Monserrat written behind
- The logo alone
- The logo alone format png 28px x 28px (this last one is what most people will see, that's why it should be minimalist so that it can be easily recognized in a very small format)
You have examples of other currencies logo here : http://coincap.io

Thanks for your help

Mathieu
