As an option to your clients to expand your availability. Its fine as far as it goes. However if the client does not have an alternative location readily available (Private Residence, Hotel Room (for the out of Towner's Traveling through)). That could be a problem. Some (assuming they don't pick you up) will not want to incur the additional cost of Transportation and/or a Room + your rate. You may be better off offering Car Service again assuming there is a safe location near where you live to do so. Or as some Ladies do, get a hotel room once or twice a Month for expanded incall.
