Updated 25th September 2018 :
Current waiting time is around 5 weeks from confirmation of order.
An order is considered confirmed once payment is received. Typically, I can start in on an order within 4 weeks of payment being received. On very small orders - for instance, under 5 x 7"s or just a one-off 12" - I may well be able to fit them in between other larger orders and do them sooner, though this does very much depend on schedules and circumstances.
Give me a shout, and I can let you know the exact situation !
