7. to guide and instruct them?

[notletrest]

hi,
Please note I'm not a teacher nor a native speaker.
Now having them two sentences is't much clearer what it is all about.
I think it's only matter of order or punctuation.
Could you do us a great favor for our future visitors to guide and instruct them?Would you write something in English?
Could you do us a great favour?
Would you write something, in English, for our future visitors to guide and instruct them ?
(not sure about the commas)
Could you do us a great favour? (it is) For our future visitors to guide and instruct them; Would you write something in English?
(in spoken English, it's could have been omitted before for our.)
Cheers.

If so , as we know before an infinitive ,we often use for to introduce its logical subject.then, who do them refer to?It should use themselves instead of "them", I am afraid.Many thanks.

Now that we are more clear about the purpose of the message, how about putting it like this:

Could you please do us a favour by writing a guide in English for our future visitors to use.

It is about getting help to write a guide, isn't it? Not actually 'to guide and instruct' visitors personally.

The font in your last post is fine. Times Roman was the font you previously used.

Thanks for a teacher who gave the answer:

"To guide and instruct them" modifies do. It acts adverbially. It answers the question "why"."I am satisfied with it.
