title: Service contract - how much should we charge for 12 month service contract
body: <p>We just finished a small project for a client (~35k), and the client would like to open a service contract with us to respond to any issues within 4 hours.  The client would pay a monthly fee regardless of if there are any issues or not.  Since this is a new product, it is likely that there will be issues, but we think that they would be small.</p>
  
  <p>We're in Salt Lake City, and the client is as well.  We're using a c# front end and mysql backend.</p>
  
  <p>I've read that some people charge by the hour after fixing bugs for free the first 3 months.  </p>
  
  <p>Should we go with a service contract and how much should we charge per month so that we don't shaft ourselves?  Or should we go with an hourly rate to fix issues as they come up?</p>
