If you wanted a "taste" of heli-skiing, an alternate idea for you is to do a day trip from Banff.
RK Heli Skiing offers a great trip from Banff at a cost of around $1000. Last year a 3-run package was $700 and a 5-run package was $900. The trip includes transportation from Banff, as well as breakfast, lunch and snacks before you drive home. A great option for you, if you're on a budget.

Otherwise, heli-skiing comes with a luxury price tag. Canadian Mountain Holidays offers 3 day, 4 day and 5 day options as well as the week long stay. Generally, the 3 day trips do not run frequently. Ball-park pricing for 3 days is $3000 and 4 days is around $4,500. If this is within your budget, it's a once-in-a-life-time-trip. Contact them directly to answer all of your questions.
