Dad has been doing the small engine thing for a few years now and is starting to get burned out. Lately he has said how he misses lawn care as he actually had his own LCO several years ago but always stayed small and part time (10 yards or less). I'm at the point where I need help as I've about maxed out all I can do. We've worked together a few days when he was slow and the 2 of us could bang out some yards pretty quick, but each time he wouldn't take any money as we always kind of trade work out (I'd help him in the shop on weekends or rainy days). If I had him work with me what would be a fair way to pay him since he already knows how to operate the equipment, I can use his dealer number to get parts cheap, and of course it's dad. I was thinking somewhere around 25% of gross as I feel he is worth more then 2 employees who don't know what there doing but also everything is mine and I have to cover the operating costs and such. I plan on doing a large adverting gig in March & April to try and gain 50-75 customers which is going to cost nearly $2k. Any advice is appreciated.
