I’m thinking an angel would be best. Which angel should one evoke for more courage/ego and eloquent speech?
I don’t want to be afraid to talk to people anymore, I want to have more personality and feel more confident/powerful inside but not in an authoritative manner, one that will attract people lovingly and make them feel spellbound by me.
You might do better with a planetary talisman unless you can reliably contact spirits and hear them.
This one could be Sun, Jupiter, Mercury, even Mars, do some reading on each and use your intuition. 
The best book on this IMO is How to Make and Use Talismans by Israel Regardie (ISBN: 9780850302097) - easy to understand and he gives examples throughout.
Try reading this as well: http://www.skyscript.co.uk/7bodies.html - it dicusses how this system can be understood in, among others, a Christian belief system.
Ok thank u
