well.. if you really cant manage a client at least every two months, i would think your design career would go down the drain soon.
I know there are ups and downs, some months you might get 5 people, some months you might not have any.. so I average it out.. if I think your doing good I would still keep you... if you have a dry spill though for more than 4 months I would have to rethink the free hosting to maybe a discount hosting plan
