Urgent Australian Email Mailing List & Campaign Setup

I have a service ready to launch and only today to put it in front of Australian real estate agents, buyers’ agents and mortgage brokers. We will have to get access to contact/mailing list as we do not have an existing list... (Budget: ₹1500 - ₹12500 INR, Jobs: ActiveCampaign, Analytics, ClickFunnels, Email Marketing, HTML, Klaviyo, Mailchimp, PHP, Unbounce, WordPress)
