Looks like what you need here is pretty straight forward. We'll get this built on the Wordpress platform, where you'll be able to insert your write up for the game and your selection, as well as add a picture for the post. This will feature on the front page, with a link to the post/selection. Below that you'll have a nicely input email newsletter form to gain subscribers for either your Free Picks or whatever you so choose to use this for. Your top navigation will include a Home, Overall Statistics, Sports Odds and will feature the current date. We'll also have 2-3 spots for advertisements (468x60 Banner in your Header) and either 2 468x60 Banners on the bottom of the homepage, or 1 728x90 Banner on the bottom. We can also do a sidebar if you'd like with potential advertisements there.
We'll include Membership where users will have to sign up to receive certain content (such as paid picks) which you can have all payment done through PayPal as shown on your page.
Basically, all you'll have to do is add a new post daily with your picks and/or writeup, and it will automatically feature on your front page. Also, you'll have to manually update your statistics page (can just copy and paste from your Excel spreadsheet)
If you'd like to contact me via Private Message, I can give you a basic outline of the design.
