B2B Advert - repost

Dear all Background: The client is called Eurodiet. Eurodiet are a wholesale weight loss company. The wholesale company (Eurodiet) want to advertise their products for other businesses to sell ("business 2 business i.e. B-2-B advertising"). I need help with the design aspect of this advert. The design will be similar to previous campaigns to follow a theme - this will be provided when the project is accepted. The advert is to be emailed to the prospective businesses therefore needs to be in a format suitable for emailing, however, must also be as close to a4 design so that it can be included in magazine for printing if required. The design must be at lest 300dpi minimum. Please ask for clarification on any of the above. Kind Regards Deven
