Unlimited FTP Accounts

Security risk. Turn it off and use sFTP.

Remote MySQL

Security risk. Bind it to your local loopback, or run it off an internal IP.

Be careful of any host that offers you 'too good to be true' plans at ridiculously low rates. Bargain servers are usually that, bargain servers. I'll stick with Linode (used to be Slicehost, but they're starting to suck bad). Other than that, I wish you the best with your startup, and I hope you're successful!
