good luck TIO... I understand bout all of the things mentioned, I have been at it for 29 years now & its not getting any easier either. BUT its all I know!!! so im hoping to keep at it another few years but just start taking the easier jobs instead of all the big jobs.... please keep in touch & post a few pics of the mixer... I think that will be a great business to start homeowners will always want a sidewalk or this decorative landscape curb stuff is very big here lately!!
