Lesser Restoration is free

If you’ve got someone willing to cast it for you for free, perhaps. But according to the PHB, most NPCs will charge far more than a typical peasant or low level adventurer could afford.

Hiring someone to cast a relatively common spell of 1st or 2nd level, such as Cure Wounds or Identify, is easy enough in a city or town, and might cost 10 to 50 gp (plus the cost of any expensive material components).

And that’s if you decide a spell that primarily exists to cure fairly rare conditions is common enough to fit in that category.
