I am looking for reliable transportation services for a corporate event scheduled for next month. The service should include a luxury van or minibus to accommodate 10-15 people, with professional drivers who have experience in corporate transportation. The event will take place on the 15th of next month in downtown New York. Preference will be given to providers that can offer both transportation to and from the venue, as well as any additional services like refreshments. Quotes must be competitive, and I require confirmation of availability by the end of this week.
