Party Invite Design

I would like some one to create party design for 7 year old boy. I have idea of what I want but can't draw ... It is a bushcraft & bouldering party so liking for cartoon of dark haired boy stooping over a basic campfire plus a second image of the same boy rock climbing.
Limited budget but I can provide amateur sketch for someone to then convert to professional drawing so hoping it can be done pretty quickly.
Need fast turnaround time
Thanks
