Two (as yet unreviewed personally), but highly recommended sites for small business advice with loads of free info:
This was referenced in a 'Small Business for Dummies' type book which indicated this site refrained from alot of extraneous advertising and got you straight to the info.
This was given to me by an experienced advisor from the Small Business Development Center. They are a resource available in my area associated with the community college. FREE small business advisors! So lucky to have such a service. Especially look at the archived articles within this site, covers all topics (marketing, taxes, you name it). You can subscribe for their newsletter free I think.
