Totally random response but I will be there at the end of March also. Actually am planning on being on Easter Island on Easter. I found a name of a guide, his name is James and his website is esaterislandspirit.com. Since I am solo I was not able to book a tour, but maybe you and your travelling companion can have him take you around. He was highly recommended to me.

Tito rapa nui tour : tito is a pascuan. He came to France while young to studio spanish.
He speaks english, spanish, french, portuguese and rapa nui.
We do with him two hikes :
One along the north shore from ahua tepeu to atakena beach
Other around Poike, east part of Island
He do also classic visit by car and had a boat
His website is underconstruction but you can contact him by Facebook or arriving at the Island.
Everybody knows everyone there...
And hiking is easy and you will see a lot that others didn't even imagine it exists...

The private tour guide we hired in Easter Island was fantastic. Her name is Josie Nahoe Mulloy - she is the granddaughter of William Mulloy, an archeologist/anthropologist from the original Thor Heyerdahl expedition who went on to devote his life's studies to Easter Island and re-erecting the Moai. He is given a lot of credit for reinvigorating the island's cultural heritage and the latter day success with tourism once the Moais were re-erected.

Josie is half Rapa Nui - she grew up in the States and took a degree in anthropology and then an MBA. She worked as an investment banker in San Francisco during the halcyon dot com days, but 12 years ago decided to leave San Francisco and return to her Easter Island roots - she subsequently married a Rapa Nui man and is now well established as a guide.

She highly recommends sunrise at Tongariki (the photos ops at dawn are stunning) and also explores different out of the way places (lava tubes, the peak of the island, etc).

Hiking to some "hidden" archeologic treasures is a must-do.
