Or, learn to do it yourself. Developing B & W is not hard and it doesn't require a lot of expensive equipment. Its really kind of fun. I haven't done it for a long time, but it was neat to open the developing tank and see those negatives for the first time.
All you really need is a developing tank, with the appropriate reels, a good thermometer and a source of running water. A changing bag is handy, but a closet or bathroom that you can seal to be completely dark will do just fine. You only need to load the film into the tank in absolute darkness. AFter that, everything is done in daylight.
BTW, ASA stands for Ameican Standards Association. ISO stands for Internation Standards Organization. In the olden days, when your K1000 was new, ASA was the authority in the US. Sometime between the sixties and today, the ISO adopted almost identical procedures for rating film sensitivity, as those used by ASA, so the two numbers are, for most purposes, interchangeable.
Back then, many film emulsions were slower than ISO 100. Kodachrome was, for many years, ASA 25. The last Kodachrome was ISO 64. There was a version of Kodachrome that was ISO 200, but that was discontinued several years ago.
Some film shooters expose their film at ASA/ISO settings above or below what the manufacturer recommends. They do this because they like the way it affects the tonal gradations, or because they need a faster film. The latter is called pushing the film, and you compensate by leaving the film in the developer a little longer than the instructions call for. This sort of thing is especially prevalent with B & W film.
