Can a committee member be paid for doing maintenance of common property?

I am secretary of our ex.committee, live on the premises of our strata complex and wish to take over maintenance of lawns and garden (common property) for a monthly fee. I am most unhappy with the current lawn mowing service and parts of the common property are not looked after at all. Would  this be  a conflict of interest (committee member being paid) or above board with approval of other committee members?
