As far as ringers, they aren't tough to make. I'm not sure what you are looking for. Some people want ringing or alert sounds and other people mean clips of pop songs. Making loops or clips of mp3 or wav files isn't too tough. I'm sure there are threads here on how to do it. If you have a sound you want made into a ringtone you should be in good shape. If you are just looking for pre-made ringtones it might be harder. Lots of companies are looking to cash in on the ringtone market since it takes almost no effort to make one but many people will pay a buck or 2 for each one. In addition, companies like to charge a dollar or 2 just for a clip of a song and if you're like me, you probably think that is bullsheet. You buy a 15 song CD for $15 but you have to pay the same price per song for just a little low quality clip...
