Hello,
My name is Cameron and can do what you want, including the vocals. Give me a shot and you won't be disappointed. To prove my skill, I can either send you a song I made up myself or I can make up a new song as an example for you. I don't have much of a resume or portfolio, but that isn't due to lack of skill, that is due to a lack of job. Mika's style is actually pretty easy for me to understand.
Yours Truly
Cameron
