English to German translation of a personal letter

Dear Johanne,

I have received both the translated letter and the invoice. Thank you! I am very lucky this week indeed to have caught you during a short gap between big projects (now I’m kicking myself for not having bought a lottery ticket when my luck is up). Thanks very much for the wonderful translation that is also delivered in such speedy manner (and the extra good luck, too!). I couldn’t have done nearly as good a job myself. Will definitely come to you first the next time I need a translation!

Best wishes,
Michell :O)
