Here's the sole proprietorship form, it's actually one page: http://www.hamburg.de/Dibis/form/pdf/Formular-Gewerbeanmeldu... – but obviously it depends a lot on the individual circumstances (like the tax ID you need for cross-border transactions). VAT is annoying, but it's only monthly if you're above 120000 Euro or so. We've started only filling in our revenue (which I can get within a few seconds) and file the tax we paid to suppliers with the yearly declaration. It's much faster to do it all in one go.
