Damaged knife blade repair
Professional sharpeners here (The Netherlands) would charge around 50 cents per centimeter of knife or, more common, just 5-6 euro per knife, regardless of size. 

You paid around 10$ per knife (9 euro and a bit). The price of the knives alone (150$ for 14 knives 12 years ago, let's say 190$  corrected for inflation) doesn't sound like a price I expect to pay for quality knives. 

My advice: If the prices for sharpening are anything like they are over here, scrap them, invest in good knives, and maintain them. 

Good whetstones aren't cheap either, and given the state the knife/knives is/are in, you'll be whetting for some time to come, unless you go hardcore, and do it the belt sander way. 

In addition: Think about if you will like sharpening knives. It's not a 5 minute process, and, as Rumtscho mentioned in his answer, it will take practice (indeed: DO keep that old knife around for learning how to sharpen!). 
I happen to like it, I find it a very meditating thing to do, but one knife will take 30 minutes for sure, and that's when I don't go all the way to the 10000 stone (I really, really like sharp knives). And depending on how picky you are about maintaining the sharpness (and how much you use them and on what), it's not a yearly drill too: Every two/three months they're up for sharpening, while in the meantime stropping them before use.

It can be pretty steep investment, but good knives will last a lifetime. I tend to keep in my mind what my grandparents used to say: "We're not rich enough to buy cheap". Cheap stuff you'll have to buy again and again. And again. You're better of with a one-time bigger investment.
