a) I hope everything goes very well for you.
b) I hope everything for you goes very well.
**** NOT A TEACHER *****
(1) I did some googling, and it seems that "I hope (that) everything goes well
for you" is the
usual order.
Most books tell us to place a prepositional phrase (such as "for you") as close as possible to the element that it is
modifying. As emsr reminded us, "for you" modifies "goes well." That is, it answers the question: goes well for whom?
(2) Question: Is "I hope (that) everything
for you goes well" an example of "bad" English. Of course, I do
not know.
I only think that some (a lot of?) native speakers might consider it
unusual but not "bad."
(3) I went to the "books" section of Google because I was hoping to find many examples of this "unusual" order. I
was very disappointed. I could find only three examples after checking 20 pages of results. Here they are. In the
parentheses, I have written what I
think might be the usual order:
"I wanted everything
for you to be better." (
The Joy Luck Club, 2001, by Amy Tan) (? = I wanted everything to be
better
for you.)
""I've done everything
for you I know how and you do this to me." (
Native Son, 1940, by Richard Wright) (? I have done
everything (that) I know how [to do]
for you and you do this to me.")
"... do everything
for you that is in my power." (
Who is Alexander Grothendieck?, 2011, by Winfred Scharlau) (? ...do everything
that is in my power
for you.)
