DanaRicard,
to All Things Plants from me too! I agree with Christine that you should edit and delete your phone number from your above post. To be safe, it's never a good idea to post personal information like address, phone number, e-mail address etc. on a public on-line forum where anyone can gain access to it.
Regarding Angel Wing Begonia's ... there are many different varieties and I googled and found a few places that sell them; I've also posted links to our recommendations page so that you can read the recommendations from other members who've purchased from these particular vendors:
