Hi ultrsea,
there are still processors out there, they advertise on the internet. One of the larger ones is probably B&H in New York. You can also find them in the Photo Magazines, like shutterbug.
You have to look for their E6 or C41 capability and mail the film to them.
For b&w negative, I recommend to try it yourself, it is so easy. The investment is very low, especially if you buy second hand on ebay or so.
Have fun!
