If you have up to three English words you’d like to have rendered in Sanskrit, Kiran Paranjape - an orthopedic surgeon in India - will do it for you for free, and very quickly. Go to his blog and scroll down a little until you see the form to email him for instructions.
He’ll also translate one to three words into other languages, including Bengali, Japanese, Chinese, and Hebrew.
You might not even need to submit, since he’s already translated thousands of words, phrases, and names, which he posts. “Love” and “peace” are pretty popular. And there’s “sister,” “know thyself,” “no regrets,” “forgiveness,” “strength,” “honor,” “thank you,” “Be the change,” etc. People have paid a little more for longer phrases like “Live and let live,” “Faith justifies neither violence nor ignorance,” and “Enveloped in rich mysterious flesh.”
