The question is do you have the tools and skill level to accomplish this?
First you need a hole saw for the size required, this drill bit with the arbor costs about $50.00 maybe more and extra pilot bits, couple bucks each.
Next you need a variable speed mag drill, low speed and feed rate required here, you can try this with a half inch drive right angle, if you are steady enough and possess exceptional dexterity.
Either tool can be rented for aprox $60.00 for half day, mag drill a little more. They might even rent you the arbor but you will have to purchase the bits, a one inch hole saw about $15 plus the pilot bits.
Three to four hours labor.
More if sink needs to removed from counter and re-installed.
