PS - A policy such as ""our minimum fee for a xxxxxxx is $ yyyy"" will save you a ton of time spent with tire kickers. Whether it's a report or an import or a script I believe minimums help set a budget right up front and lets the person inquiring self-qualify.
Be advised - the VAST majority of web inquiries are companies looking for either free quick questions or someone willing to bill in 1/10 of an hour increments at rates dating from 1985. And all initial discussion, scope, discovery, planning and project management should be non-billable.
