Multisite on Bluehost (Subdomain Setup)

Are there plugins that can help me while using Bluehost which may or may not support the following when developing a WPMultisite Network:

(1) Dynamic DNS;

(2) Dynamic database; and

(3) User creation.?

I’m asking this because I am having issues with Multisite on Bluehost. Yes, I already did a wildcard subdomain. Did it lastnight and it is still not working right.
