I need some ideas about membership website?

[The Real World]

Hi,

Today I am writing in yahoo answer for good ideas. Please don't tell me any inappropriate ideas. I need good comments for good decision. Finally, I have decided to create an artist’s directory membership website. I will gather various types of contact info for every artist in USA and then other countries. I am going to be creating an artist’s directory. My website will be charged for 29.95 USD per month for standard membership.

For every artist I will gather following information listed below:
Twitter
Facebook
Google Plus
Youtube
Wikipidea
Lasr Fm
ilike
Rss
Myspace
shop.bravadousa.com
bandcamp
soundcloud
Google Map
Phone
Fax
Location
Street Address
Vimo

Question 1: What do you think is it right decision?
Question 2: What is the importance of artist’s directory in the web? How is it important in the internet?
Question 3: Is there any similar artist’s directory with all contact details of all artists in usa?
Question 4: What do you think about this business? I want to create this artists directory site as a membership website. What is my success rate?
Question 5: For US how is it important if I collect all artist contact info in one website?
Question 6: How much people search artist’s directory?
Question 7: Am I wrong with this idea? If I wrong then correct me and provide your great feedback.

Please tell me your good suggestion. I am sharing my ideas in yahoo answers big community for choosing right decision. So please correct me if my decision is wrong. If my decision is wrong then tell me for what types of content can I gather for a good marketable membership site.
I hope that I will get appropriate ideas from yahoo answers users.
Thank you so much for your time.
