Sounds very negative in tone.
There's nothing I'd say was particularly heinous in there, but the whole thing does come off (to me) as a bit tentative and apologetic. You're not wasting his time; you're offering him your services, which he sought out. I'd rewrite the communication to sound more professional, with less colloquial English; just because it's an informal email, doesn't mean it doesn't contribute to his opinion of your professionalism.

Also, there are too many kisses, mostly in the opening. Just put one or two at the end.

He may be a shirter though Monty.
In which case, there are not enough kisses.

I don't receive enough emails with kisses in
I would like more. The kisses should stay.
