Thanks in advance

Business writing can be difficult if you are normally a polite person. If you are not... don't bother reading on... you are an ass and probably haven't the need to ponder this.

Often many requests for action need to be made... however the limited number of synonyms for "please" makes it difficult to be polite and not be repetitive. Fortunately, one word bails me out... the word is "kindly". Kindly see it in action here:

PLEASE find the enclosed surgical needle provided for your convenience. KINDLY insert it into your eye until blindness is guaranteed.

This is where I am stumped.

What happens when you have a third sentence requiring polite instructions be given? Do you re-use the "please"? re-use the "kindly"? or is there a third word? or even a fourth word? or maybe a phrase like "thanks in advance"?

Hmmmm.

Please ponder this business writing dilemma.
Kindly provide your findings via a comment to this post.
Thanks in advance for your swift attention to this request.
