Konban wa minna!    
Ware wa Simon-chan.　　

when "ware(われ)" is used as a first person pronoun, it sounds a bit arrogant, so it's almost falling out of use in public occasion. They use "watashi（私＝わたし）"or “watakushi（わたし）”instead of  "ware(われ)". And young men can also use "boku（僕＝ぼく）".

=>はじめまして、よろしくお願いします。simonです。（hajimemashite、yoroshiku onegaishimasu。
simon desu。）

"hajimemashite(はじめまして)" is used when you meet a person for the first time and introduce yourself.

"yoroshiku onegaishimasu(よろしくお願いします)" means something like  "Nice to meet you".

"simon desu(simonです)" means "I'm Simon".

Hope these help. @_@
