Just to get to base camp is a bit of a feat itself. Fly to Katmandu. Take a puddle jumper to one of the most dangerous airports in the world, Lukla. One way dead end runway at 9300 feet. About a week overland trek to basecamp at 17,600 feet. Have to acclimate to the elevation. Cost $40K to $60K to climb Everest with sherpas lugging all your gear. Almost no one climbs Everest without fixed ropes going in first which are done by sherpa teams. One of my wishes is to just see Everest. 12,000 relief mountain puts our New England hills to shame.
There is another option and that is to climb from the China side. Bit more technical but I think easier access
