Most celebrities have a few of their own 'pet' charities, which they support in their own way. Linking celebrities to charities is not unusual, but can only work in the following way. The exception is when a speaker or artist is being engaged to perform at an event or dinner where tickets are being sold to pay for the performer or speaker. Asking a celebrity to donate his or her fee to charity is also not the greatest of ideas. Marketing sometimes requires mailing requests, questionnaires, invitations etc directly to celebrities.
Fees are subject to requirement.
CMM can also contact the celebrities to check progress if required. This latter service is a very effective way of delivering celebrities to parties or premieres etc. Most personality's images can now be found somewhere on the Internet. Capitalise your search name. Use different search engines if no luck.
