Email marketing

I am trying to promote my Seminar via E-mail marketing to medical students and new graduates, particularly international medical students. They include both US persons and Canadian citizens who went to foreign schools (particularly those in the Caribbean), and foreign-born medical graduates attending foreign schools. Many will be applying to US residency training programmes. My Seminar is to assist them with writing their personal statements and equip them with facts and confidence for interviews. The service is only for applicants interested in family medicine and primary care internal medicine programmes. I like to get this going ASAP. How can you help me and how much would you charge
