I don't have time to do contract work, but you may want to look at Shipping Director. One caveat though - the trial version there is expired - I'll be updating it this week. Look at the blogs for common (and not so common:) shipping scenarios. You can PM me or use the Contact Us page there if you have any questions.
We have a small business here in Western NC, using 2.4 version. www.fsfireplace.com
I have used a developer in the UK for custom work and upgrades and he has been most helpful, prompt and cost effective to work with. I don't know if he has time or can do what you need but you might email him and ask.
Our developer recently set up a new nopCommerce site for us (2.3) and we need customization work that the original developer does not have time to do.
Looking for: shipping plugin development (C#), & customization of invoice and shipping order PDFs.
