TSS (Subclass 482)

Hello, we're a business in Brendale and require a technician to perform service work and staff training on some technical equipment purchased from the USA. He's in Ecuador and is a subcontractor of the US company from whom we purchased the equipment (long story). The US company is paying him not us. I'm looking for assistance to complete the necessary Visa applications, sponsorship etc to have him come onsite for about 3 weeks. Prefer someone local and a registered migration agent.

I've been researching and navigating through the Dept. of Home Affairs website but don't have the time to invest in what's required. Looking for someone with at least 5 years experience in assisting with Visa applications.
