Replying to Alpe d'huez to les deux alpes

basically this summer in my uni holidays i want to get a job in the alps and i want to go to 2 alpes to ski and bike and just have an amazing summer, now i have heard that summer jobs are competitive, so anyway a friend of my parents said he could sort me out with a job in alpe d'huez for the summer which sounds good, so i was basically wondering if i spent the summer there are there public buses which go to deux alpes as it is just over 40 mins away or are there lots of people driving as i wont have a car, or would it be better to try and get in 2 alpes. plus k to any responses not to sure if this was the right place to post this
