I'm mirroring much of what Nathaneal wrote.
How often to you dry clean?
I have a steamer to de-wrinkle the clothing and a simple airing out in my woolen closet.
I'm thinking of building a screened it closet on the back porch for a better moth free airing out place.
Really if you don't get them dirty, simply steaming and airing out will do the trick. You may have to iron the pants to crisp up the folds.
what are you wanting to dry clean? suits?
Shirts, pants and suits.
Ho often are you drycleaning clothes?
Why are you dry-cleaning shirts?
I use a laundry for my dress shirts, simply beacuse the cost:benefit ratio is in favor of the laundry. BTW, I include the cost of my time for ironing dress shirts in that calculation.
