Build lead database of event managers

Hi, I wish to build a database of 100 leads of event and conference organisers within large companies in Sydney or Melbourne Australia. Target: - Employees with the following words in their job titles: Event, Events, Conference, Conferences. - these are people within a company who organise their company's conferences and events. - they are not from professional conference/event companies that work externally to a corporation and act as a supplier to them. (That is another list to develop later). - these need to be from Sydney and Melbourne, Australia. - these need to be from the top 5500 ASX companies. Ie the largest publicly listed companies. - focus is on banks, finance, pharmaceutical, telecommunications - I need their name, company name, job title, phone numbers and preferably email addresses. - In many cases there should be at least 5 in each company, so it quite likely this list could be 500 names. I have 2-3 other lists I'd need compiling once this is done. Many thanks It would be best if 20-30 names were supplied, I checked them, then another 100, then the final list. I then need other job functions
