Define your work/time and apply reasonable fees. Bear in mind that larger accounts generally go for "lowest bid" while small accounts are turn key, one-time events. Compare long term relationships to single events. One should generally charge higher for the short term...which recognizes there might be no return business, and slightly less for long term which will be continuing.

In the end, charge what YOU consider fair for your work/effort. If you aren't doing that already might want to rethink! :)
