Pop open the phone book. And look up "Sewing Machines"
Note: I did not say click open yellow.com!
Now that you've got that big book in your hands look up sewing machine. Look at it really look at it. First will be listed the dealers, but then you will seem them the little ads. Sewing Machine Repairs -they will list the brands that they repair. Go down the list it might be short it might be long, but a list all the same.
Now that you have those names pick up the phone and call the people. How much for them to look at them. Some places charge to do this and others are free. Not all sewing machine repair people are nice. My repair guy for my sewing machine is a very "brisk" man. Not my favorite person in the world, but he can get his hands on any and every part that I can break. Oh be weary some dealers fix machines and sells new ones - which is not always a bad thing, just be firm that you'd like yours repaired.
There is no doubt in my mind that your machine can be repaired, and most likely for less money than you think. Give that phone book a chance.
