Can someone please give me suggestions for voice programs to use?

As some of you may know, I'm planning to go full-time at the end of this summer.  This means a lot of things, but the one I'm most concerned about is voice!  I would like to hear all of your opinions on which programs would be the best to train my voice over this summer (May 6th to August 29th).

I'm really taking this period of transition seriously and working on my voice, appearance, etc. will be a really big focus of my summer.  I'm really excited about all of this, but I'm a little scared that my voice won't back me up in the end!  This is why I would really appreciate learning from some of you more experienced girls about what worked for you.

Thank you.
