I would second the area around Lauterbrunnen. There is a hostel there (~25 sFr), and a relatively inexpensive B&B (~30 sFr, right across the street from the Protestant church, with lots of flowers on it). If I remember correctly, there is also a campground further south along the road in Stechelburg.
Since you're alone, I couldn't recommend doing much unguided. You could hike (completely untechnical) the Schilthorn after catching the lift (~7 sFr) to Grimmelwald (not Grindelwald). The Shilthorn gives great views to the entire Berner Oberland. There is a lift to the top, and many tourists hike down from there, so I would be comfortable going solo. Expect a 5,000-foot elevation gain from Grimmelwald.
It is expensive, but worth every Franc to take the train from Lauterbrunnen/Interlaken/Wegen/Grindelwald to the Jungfraujoch. Again, lots of people, but well worth it. You can hike from the Sphinx train station to the Mönchjochhütte (a hut around 11,000 feet) in about 40 minutes. The glacier is packed down with snow equipment, so you don't need a rope or a partner. Staying at the hut costs around 40-55 sFr, but is a great experience, and probably about the closest you can get to a mountaineering experience without hiring a guide or finding a partner. If I were back there and alone, this is where I would go. Highly recommended. If you do it, bring lots of water, as water is very expensive at the hut.
The Zermatt area is more touristy than Lauterbrunnen (more expensive). You'll have to camp if you want to stay there for under ~35 sFr/night. There are miles of hiking trails all over. As far as I know there isn't any camping in the nearby Saas-Fee. I'm not as familiar with the the Valais region.
Again, if you are looking for good hikes to do solo, the Gross Mythen near Schwyz would be an excellent choice. The trail from Brunni is a quick 1/4 day walk. In the French-speaking pre-Alps, I also recommend the hiking around Villars, Leysin, and Les Diablerets.
If you are going toward the end of September, you'll be hitting the area at the end of the summer season. If you're lucky, most of the tourists will be gone. I managed to find a few B&B owners who were willing to give me very, very reduced rates if I stayed multiple nights and skipped breakfast. They were just happy to let out their guest-room. Grab breakfast at the local bakery, and you could stay at a B&B for the price of camping. Worth keeping in mind.
If possible, try to make your schedule flexible. You could end up in the Jungfrau or Zermatt region, spend five days in the clouds and rain, and leave on the first sunny day. It's a small country, so if it is rainy, go to the sun. You'll likely only lose 1/2 day.
Enjoy!
