mls listing

Hi all!

I'll be building a state-wide real estate site and I don't have any idea how big the data archive for this. Well, I ran a test site, imported MLS listing for one real estate property and it was able to pull a record of more than 100k items. Any advice from the experts of which of the server options should I avail for this project? I appreciate your quick response. ;)

These are my options.
