New Agent with $5 Million Listing -Need Advice!

[Gina Ventimiglia]

Hello, I just got my license about 3 months ago.  I work in a small, private brokerage that also just opened, although the broker has been in the field for about 22 years. My first listing is $4.9 million in Viera Florida.  Being that the brokerage is small and new, and we are all mostly new agents, I don't have a large, experienced "team" to help find a buyer, so I am pretty much on my own trying to navigate the selling process of this home. The ideal buyer would be an out of state, cash buyer/ investor.  
 Does anyone have any advice on how to approach this scenario?  Any successful stories, websites, routes to take or NOT take would be greatly appreciated!
