The name Guy in Hebrew letters is גיא. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
גיא
In short
Your name in Hebrew letters is גיא. “Valley.” A word from the Torah: “the valley opposite Beth-peor” (Deuteronomy 34:6). Adding up the numbers of its letters gives 14 — the same as the Torah word יד, “hand”. That number points to Torah page 14 of 354 — in the portion Noach. What that portion is about: The flood and the ark; the rainbow as a sign of the covenant; the tower of Babel; ten generations from Noah to Abraham. The verse that begins with the first letter of your name and ends with the last is Proverbs 19:2. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Guy” — this exact spelling is what was calculated: גיא. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name גיא gives 14.

This is from the portion Noach. What it is about: The flood and the ark; the rainbow as a sign of the covenant; the tower of Babel; ten generations from Noah to Abraham.

For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name גיא does not stand as a separate word in the Torah, but appears 3 times with prefixes — first in Numbers 21:20.
