Do you intend to keep your gear and take it home?
You can find a shop that offers what's called a "season lease" which should be around $200-$300, and allow you to try different skis as you learn over your long vacation. This will be especially good for beginner/intermediate as you do not want to purchase those skis. It will also give you a chance to go back and change out gear that you don't like.
If you are more serious, then please read the articles. The next stage up is to buy new boots which is the most important piece of ski equipment, and somewhat custom to each skier, then continue with the lease/rental of just the skis.
Next, you can demo different skis, then buy something new (or used). Many shops offer a program to allow you to rent for a few days and then apply your rental fees towards your final purchase (usually at the full advertised price).
Unfortunately I am not certain which shops may have the best season lease program. You should call shops to ask if they offer such programs as it may not be on their websites; and or ask about any options regarding purchase before showing up.
They will definitely have something similar or a discount if they know you are planning to rent for long period of time
