If another pair of eyes would help, I'd be happy to beta for you -- just pop me an email at this username at gmail. Either way, good luck with the wrangling!

And I'd hazard a guess that your words are better than your nerves are telling you. Having seen examples of your writing, and having had extensive experience with that doubting voice, both in myself and with friends and acquaintances, I feel well-qualified to say so. ;-)
