I think that depends a lot on what you mean "a decent attorney". Sure, a partner at Proskauer isn't going to take your call, but in my experience, the nice woman with the office down the street might be glad to help you put together a plan, critique your demand letter, etc. This kind of "decent attorney" is willing to work with you on the small stuff, in the hopes that you'll come back to her in the future with bigger business, and refer your friends and family as well.
A piece of advice -- as you mature and your life becomes more complex, it's not a bad thing to have a good relationship with an attorney. Here are some situations that have come up in my life:
Reviewing my ISO and non-compete agreements when I took a start-up job
Getting my security deposit back from a landlord who would not pay up
Reviewing the sale agreement for same start-up 10 years later
Representing me at closing when I bought my first home
Advising me when my bank "misplaced" a $10,000 deposit for over a month (they cashed the check but didn't credit my account)
Discussing will and estate planning when my first child was born
For all of this, and probably some other things I'm forgetting, I probably paid him less than $2,000 total -- and half of that was in closing costs on the house.
More recently, a different attorney (I moved) handled another landlord-tenant dispute for me with a couple of letters to the landlord's attorney, and never even sent me a bill.
