Help with image for branded event wear

Hi sorry if this is in the wrong area but not sure where else to put it.

I need help with artwork I need for event wear for a charity I volunteer with.

I have tried to do the artwork myself but struggling as I can't use photoshop etc!

I was wondering if any of you could spare an hour or so to help with this?

We have a colour logo and I need it to be black and white outline only.

Thanks in advance,

Lisa
