Build a Website

Hello, I am looking for the following items for our site and would like to see what the cost would be on this or if it is some or all is even possible. 1. Wanting to see if we can have each visitor create their own profile. This profile would keep track of their email address and other info we would like to collect. We would even like the option for them to sign in using facebook if possible. We would also like to be able to geographically connect the profile to their current location. 2. Individuals with profiles on our site would be allowed to post photos and video to the blog section. We will be setting up challenges on the site, so we would like to be able to set up a point system for the individuals so as they knock out challenges they collect points for each challenge they completed. 3. They will be allowed to submit their video or photo to this challenge and click submit and the challenge would be completed and automatically tally the points they earn from that challenge. 4. The admins (myself) would be allowed to review their posting and edit their challenge complete status. If we feel they did not complete it and deduct the points as we see fit. 5. We would like to be able to send email notifications, text message notifications and if possible facebook notifications as new challenges pop up. 6. On the site it would show a scoreboard and rank each profile and what their standings are and keep track of each challenge they accomplished. 7. We would also like the ability for these individuals to be able to post pictures and videos on the blog section of the page and allow others to vote on that video and/or picture. 8. We would like the ability to be able to connect people on the blog. For example, if someone posted something on the blog related to Chicago, then a person who views the blog, the first items that pop up would be Chicago related, if any existed. This is not as pertinent as the other options listed, so if it is an expensive option, then we will add it at a later date. 9. We would also like the ability for the individuals to purchase items from our site. Basically the ability to shop for apparel that we are selling. 10. We would like the ability to be able to connect to the individuals social media outlets if they allow us to. For example, if they compete a challenge on the site, when they click submit and challenge is complete, it sends a notification to their facebook page that they completed the challenge and we would post a notification on their facebook page. 11. How I see it set up. When you enter there would be a home page. The home page would have the bolg and the rankings board in the middle right. Like two columns. Blog more in the middle and rankings board more toward the middle right. On the left hand column it would have a tabs to select from. Challenge tabs, where all challenges would be located. Shop tab, where all shopping would take place. Blog tab, where it would just be the blog an a separate page. Rankings tab, where is it would just be the rankings of all members. About us tab, with a description of who we are and what we do. Contact us tab, where we give the visitors the ability to contact us. 12. We would really like the website to look as clean, modern, and easy to use as possible. Please feel free to contact me with any additional questions.
