I haven’t even started researching, I am lucky that some of my social network friends have, discovered shared links to 2 wonderful parts of the web!
Smooth draft offer editing and proofreading services – I am sure they can offer a lot of help for payment – what caught my NaNo eye was the book by EM Lynley, which if you have Kindle/ Ereaders or just under £4.oo to spare could be yours.
If not there are 2 FREE planning worksheets (PDF) which are supposed to be used in conjunction with the book. However, if you are an experienced writer they are self explanatory and fairly easy to complete.

The other is a blog which has been conceived especially for Nano.

Where again you have an amazing opportunity to pay for Accelerator which is a whole journey alongside Nano which could lead to a published Nano Novel.
Have fun checking them out.
Remember feel free to add links to resources and sites you have found NaNo useful.
