Hard to tell from your profile but you may qualify from the excellent value Conville Course. If not there are always people to join with around the campsites or in the 'partners wanted' book in the OHM office in Chamonix town centre if you are heading to that area.
Looking at your climbing profile most routes seem to be sport. So a good start may be to play to your strengths. Perhaps consider some of the alpine rock routes that do not require a glacial approach - there are loads that are bolted and will give you a feel of longer / higher routes. Aiguilles Rouges especially good for this.
Consider getting the Bruce Goodlad book and learning some skills with your mate. Find easy ground to practice moving together - well worth practicing in UK first on terrain you find straightforward.
Snow anchors and axe skills can be practiced in the Aiguilles Rouges. Mer de Glace is great to practice crampon skills, ice screw placements, top rope ice climbing and glacier travel / rescue. Then perhaps head to a wet glacier such as by the Albert Premier.
You may find Saas or Arolla great bases for a first time or, better still, follow the good weather. Have fun!
