Do you have the ability to target cities, age ranges, income levels, other? 5. If so, please provide the breakdown of who, what, when where. etc. 6. Do you have any guarantees and if so, what are they? 7. What previous experience do you have with projects like these? 8. Do you have referrals available for the successful projects? 9. How long will the project take? 10. What is your best price or how/what is your pricing? 11. Do you have access to the top Facebook and Twitter users who will also be able to market my site? I would like to find people on Facebook and Twitter who have high volume traffic and followings and utilize them to advertise my site to their friends. Let me know if you have that capability as well. Please also provide your contact information. Thanks, H
