Hand lettering during an event

As a client interested in hand lettering for a corporate event, I'm looking for an experienced artist to bring my event to life. The hand lettering will be used as signage, on skin, paper or fabric to display a client’s mantra for the year. We will have about 70-80 people in attendance. We aren’t looking for calligraphy rather someone with good handwriting. We plan to hire 3 artists and will need you for about 2 hours in total, meaning your might handle 20 of our clients. The artist should have a portfolio of hand lettering they've previously created so I can get a good idea of their style before hiring. Experience in corporate events is an added bonus. If you think you have the skills and experience I'm looking for, I'd love to hear about your services.
