Crear una plantilla para Wordpress

Hi! I want to have a new web page based in Wordpress. I have think on some things I would like the page to have: - On the home page the posts will appear with photos and the tittles on the photos. Each post will be a cause that people can join for free. That will make it more visible. Also a counter of the people that have join the cause and the author of it. - When you enter to one post, i will need that the visitors can join that cause. What I mean is that on the post, the visitor would have the opportunity to sign on one cause with the email and the name. - Once the person have sign the cause, it can share on facebook or twitter. I would like that on the visitors facebook appears one specific sentence when it shares it. - I will like to have on each cause a big description of the cause, comments from the people who have join the cause and a small box where I can update some information. This is the basic information. If you think you could do it you can bid and while you work we can talk about more details for the web!
