One of the best paying online survey companies to sign up for is Pinecone Research. Pinecone pays $3 for each survey (and they pay via PayPal too!). They are currently seeking additional survey respondents.
If you are interested in joining, sign up directly with Pinecone Research. You will be required to complete a short questionnaire prior to being accepted. If you are accepted, I would expect the surveys to start coming your way within a month's time.
