Newb to Wholesale- I have 50 properties and need some guidance

[Eamon Sullivan]

Guys. 

I have been working on Land Flipping in Florida. Sending out mailers, originally trying to buy land for pennies on the dollar. A gentleman received one of my mailers and notified me that he had approximately 50 properties that he acquired via Tax Deed. I originally thought no way, I can't buy $250,000 worth of land but maybe I could help him sell them via assignment. He agreed to allow me to sell them via assignment. 

So now I have 50 properties to sell in Florida.  Some of the properties are not worth much more than the value of his tax deed ( agreed sales price). There are a few that I may 'cherrypick'. The properties range $3k to $15k in value.

 How would you advanced/ experienced wholesalers go about this??

I am targeting craigslist, sending flyers to local neighbors, putting signs in.... what is most effective??
