Work trade! I'm a landscaper, looking for drywaller/plumber/tiler

Hi guys, I'm looking for some help building an in law suite for my father and it's a slow time of year for me so I was hoping to find someone that can do the stuff I can't and I'll trade you the same value of my work. I have references from current clients, certified in multiple areas, 20+ years experience. Or maybe you have a parent whose having a hard time keeping up with their yard, I could do a weekly visit and just send a weekly/monthly invoice of the work & value accomplished until we're even. Would prefer someone with current references so we are both getting equal value. Of course materials are not included, we each pay for any materials or dump fees etc it's the labor itself we would be trading. Any inquiries welcome.
