Looking for serious RP servers

I am looking for an RP server that has a high population, encourages quality RP, and isn't riddled with purchasable items. I don't want to be surrounded by people who dropped $100 to buy the coolest cars and houses. Very much interested in something that requires you to work for what you have. Its much more interesting seeing or becoming a successful character knowing it required real effort. I have a very high quality mic, and have been RPing for many years. Do not mind an interview process or whitelisting.
