Color Management and Zing laser

I have CorelDraw X7 and a Zing 40 watt laser.

My sister has a business logo that I want to put on a wood sign for her.

The logo has 5 colors - black, and shades of red, green, blue, and brown.  The background is white

I've tried importing the logo as a jpg and treating it as a photo but the gray shades are not distinct enough

I've also tried using color managment in X7 but so far it is just one big blob of gray when the laser burns the logo into wood.

I would like to find a tutorial or someone who can help  walk me through the steps of color management and how to set up the logo for burning to the laser. 

My preference would be to communicate directly via email (pmrii@aol.com) or I can call anywhere in the US to talk with you.

Thanks,
