Seems like you want to get your image directly converted to G-Code. (G-code is what the machine uses to make the engraving - check with the person who will do the work to get the correct format.)
Maybe you can shortcut the process?
If you have the logo in jpg or bmp form then you could use some of the 'Image to G-Code' applications out there.
There are programs like SCAN2CNC that will start with using a flatbed scanner and bypass the tablet and puck. That would get you from paper to image. Or maybe use a digital camera or copy shop to scan for you?
The following may help - sorry it has lost the screen shots but you'll get the idea:
