I would like to create a web to lead form that enables the lead to schedule an appointment. Now that Google calendar has been integrated with Salesforce it would be great if we could provide a drop down list with available dates and time slots (with a visual image of the calendar showing those dates available). If the user clicks on a specific date I would like that date to be specified as the default date in the pick list. Once a time slot has been taken (after lead has submitted their information), I would like the system to automatically remove it from the list so scheduling conflicts do not occur. When a lead completes the form not only is their contact information stored but a calendar item is added as well which is linked back to the leads record.
