An insurer is trying to help independent career firms and financial representatives share ideas.

John Hancock Financial Network, Boston, a unit of Manulife Financial Corp., Toronto, has set up a Sales and Marketing Center in the password-protected section of its website aimed at network representatives.

In addition to marketing ideas, the site offers sales and marketing packages, practice management tips, and resources visitors can use to promote themselves and their products. The marketing materials include sample letters, flyers, ads, brochures, press releases and how-to guides.
