Wedding Mirror Calligraphy

Dear Jack Found you on here and think you could be the right person to help us! We are looking for a calligrapher to help us with our wedding seating plan. This is simply writing on a mirror. Pictures attached. We would you on Friday 1st September to do this - our wedding is at Lambeth Palace so you would have to go there. Is this something you think you could do? If so, what are your prices and how long would something like this take to do? Mirror 1 is actually exactly the same as our mirror which helps you understand what we need. Really looking forward to hearing from you Megan
