I am trying to find this book by Hillel the Elder Pirke Avot 1.12. I have searched the Logos Storefront. Where is it in Logos?
Google is your friend:

https://www.chabad.org/library/article_cdo/aid/5708/jewish/Ethics-of-the-Fathers-Pirkeit-Avot.htm
And the Mishnah should be well within your budget (recommended). The Talmud (as Logos lists) is good too.
Several volumes below are especially appropo to your project.

Logos carries this (search Pirke Avot) Pirke Avot: Timeless Wisdom for Modern Life: Hebrew Text | Logos Bible Software It is the saying at 1.12 that is by Hillel the Elder rather than the book.
