This tartan (aka clergy) is usually produced in blue, and if you go that route I can do a box pleated kilt for you for $390. If you'd like it special woven in purple, though, I can make a box pleated kilt for you for $490.

I don't know from your message, but if you are considering making it yourself, the Scottish Tartans Museum offers custom woven cloth for $65/yd, 29" wide. That's $260 for a four yard length (for a box pleated kilt), and shipping would be free.
