TO: Events StaffFROM: Marinella Garnet, Project Manager SUBJECT: Upcoming Seminar DATE: September 23As announced at the recent meeting, our company is organizing a three-day business seminar on e-commerce.The seminar, to be held six months from now, will be attended by small and mid-size business owners wishing to learn how to sell their products and services on the Internet. To facilitate the planning of this seminar, I have posted a list of seminar committees and their members on the bulletin board. — [1] —.The committees are as follows:Speaker Committee Venue Committee Food Committee Marketing Committee Registration CommitteeYou will notice that, except for the marketing committee, all committees are composed of new members.The venue committee must confirm the location at least 3 months prior to the event. — [2]—. The marketing committee must coordinate with Mr. Donaldson, our marketing director, so that they will be familiar with the company’s new sponsorship packages. Since the seminar is free, I would like the marketing committee to look for more sponsors so that the majority of the seminar’s costs may be covered by income from advertisers. — [3] —. Make sure that sponsors are aware of the benefits they will receive in return for their assistance, including the use of their logos in promotional materials for the seminar.I also want the speaker committee to present a list of potential guest speakers. — [4] —. If possible, invite executives from online books, arts and crafts, computers, and clothing retailers.
