I'm not really sure how commissioning/requesting a Mugen character works, but i'm fairly certain you're supposed to say please & ask nicely when you ask for something.
Not to mention most people aren't going to make things just because you told them you wanted a certain character made.
If you want Bayonetta in Mugen form, you're ether going to have to pay someone to have her created,
which i think is probably somewhat pricey, if i remember correctly,
or, the more likelier of the two, make Bayonetta in Mugen yourself.
