You need to itemize your budget with breakdowns for advertising and promotions. Include any design, development for needed materials to facilitate the marketing. List the media outlets that will be used to execute your marketing plan and break out the online, social, e_mail marketing, e_brochures/e_catalogs, TV, print, radio, PR, tradeshows, sponsorships, philanthropic partnerships, direct_mail, telemarketing, and other outlets.
