Sounds like a great start! As PP have mentioned, you're doing an amazing thing that will help a lot of families.

I'd be happy to share our slides from past presentations if you're looking for some ideas to help get you started. I've been doing this for about 5 years now and can blab about gifted stuff for hours now but I still prefer to have material that I can lean on and keep me focused (of course everyone is different so feel free to do whatever you feel most comfortable doing).

Good luck!
