Joint business on the basis of 'one's place is another's machine' 8587579773

I bought a rice threshing machine and every year I used to make some money by threshing rice myself. But now I can't work alone because of weakness. A friend of mine has a rice mill. I planned to set up my machine with his rice mill and both of them would work with that machine. We will share equally what I earn. The question is, will it be fair for me to make this deal with him? Will be obliged to inform. 4922586881
