Help with cleaning blades on Minolta lens

I’ve asked this on a couple of forums but nobody ever had an answer. I would sure appreaciate it if anyone here might know anything about this.
I bought an old Minolta lens about a year ago. It’s a 28-80 zoomxi. I really love that lens! It’s not suited for everything, but it gives images this really cool sort hazy, while still being sharp look. Almost like there’s a built gauze filter or something. Used in the right situations, I love the effect! So, I don’t want to give up this lens.
Here’s my dilemma though – I only paid $60.00 for the lens, and it worked great for about 9 or 10 months, then it started running into problems. If I open the aperture up past about f/8, the lens wont close the aperture down again when I try to drop the aperture back up to f/11 or greater. It gets stuck wide open. So, if I go to say f/2.8 and take a shot it’s fine. Then I go back to say f/16 and the shot is WAY overexposed. The only way to stop the aperture back down is to take the lens off the camera and actually push the aperture release arm with my finger back into the default position.
I’ve figured out from talking to people that the shutter blades are probably dirty or oily and the lens needs to be taken apart and the blades cleaned. The problem is that I’ve taken it to camera techs and they all want between $150.00 to $200.00 to do the cleaning. I really don’t want to spend that much money on a used lens that I paid $60.00 for and I can’t afford that anyway.
So I was wondering if it was something I could maybe do myself? I’ve been looking EVERYWHERE on the net for any kind of instructions on how to do it but I can’t find ANYTHING. Does anyone know where I might be able to get some kind of a guide or information on exactly how to go about doing the job?
Any help anyone might be able to give me sure would be appreciated!

I don’t really have any experience with that sort of thing, but I know enough to know that camera lenses are extremely intricate and complex pieces of gear. There’s an unreal amount of parts in them — and very, very small ones to boot. You have to really know what you’re doing if you’re going to get into tearing them apart. If, when putting it back together, one of those minuscule little parts isn’t sitting exactly quite right, you can really mess up your lens.
The news gets even worse, I think, when dealing with those old Minolta ZoomXI lenses because the mechanics involved with the zoom motor.
Sorry to be the bearer of bad news, Guy… but there’s a reason those Techs are charging what they are — the job is a huge pain in the butt! And, you can easily mess up the lens if you’re not EXCEEDINGLY careful.
Then again, I don’t have a huge amount of knowledge or experience when it comes to lens repair. So, I might be talking nonsense. Perhaps someone else with more knowledge than I might be able to help.
