Replace or repair dryer vent? Who is best creature to repair/replace? have a GE dryer explicitly causing me some trouble. We've notice...

have a GE dryer explicitly causing me some trouble. We've notice in times past few days that the dryer lint is getting into the air and is accumulate also on the vent that goes to the outdoors. I don't know how the dryer is (it come with the house that we bought more or less 5 years ago). The vent is also 5 years old and have never been vacuumed or cleared out. I am concerned that it is a fire menace (and not great to breathe). I tried disconnecting the vent from the dryer but the person who installed this really jammed the vent into the dryer (and I didnt see any clamps).

I guess my cross-examine is: what would happen if I really pulled the vent out easier said than done - will I do damage?

If I agree on to hire someone to fix this, what is the best serviceperson to do so (a HVAC contractor, an air duct cleaning professional, a plumber, a handyman, etc). And what should I expect them to do beyond cleaning the vent out (ie. should it be replaced, etc.).

I appeciate any word of tradition - I'm on a budget and have a contemporary baby at home :)

Dishwasher motor impossible?
Appliance repairman. If you be a little more handy, you could do it yourself. Its not that unyielding.
