I used to build rainfall catchment in remote locations. I am not sure what your needs are or the annual rainfall where you live, but we built 11,000 gallon systems designed to fill on 4" of precipitation. We used 80'x40' steel aprons built from C-channel purlins and type b steel decking. You could pull off a similar system for about 11 grand give or take.
