It goes to show how much of a dedicated businessman you are..

[Ashraful Haque]

"The look of disappointment on your face for loosing just a few customers only goes to show how much of a dedicated businessman you are."
"The look of disappointment on your face for loosing just a few customers only goes to show how dedicated you are as a businessman."

Do the sentences convey the same message?

I hear this phrase (how much of a/you're one hell of a) all the time, but I'm not sure if I've used it correctly in the sentence above.

Few more sentence I'm not sure about.
"He has no idea how much of a loser he is."
"You have no idea how much of an asset you are to this company."

"The look of disappointment on your face for loosing losing just a few customers only goes to show how much of a dedicated businessman you are."
"The look of disappointment on your face for loosing losing just a few customers only goes to show how dedicated you are as a businessman."

Note the difference between "lose" (verb) and "loose" (adjective).

Do the sentences convey the same message?

Yes, although I'm not keen on the "how much of" version. I'd say "... only goes to show what a dedicated businessman you are".

I hear this the phrases no bracket here "how much of a" and "you're one hell of a" no bracket here all the time, but I'm not sure if I've used it the first correctly in the sentence above.

Note my corrections above.

Few Here are a couple more sentence I'm not sure about:
"He has no idea how much of a loser he is."
"You have no idea how much of an asset you are to this company."

Both of those sentences are correct. However, in both, "how much of" could be replaced by "what".
