Updating the services page. We're probably needing a new design to all this content.

The goal is to improve the content of our service pages. I wrote a lot and it can probably be improved. I think these are the tasks that will define when this PR is done:

- [x] Review of the content by @rafaelp 
- [x] Iterate over a new design to the page
- [x] Implement the new design front-end
- [x] Translate to english
- [ ] Merge on master

Please, discussions go bellow in the comments, but do not forget to check here when a task is done. Also feel free to add new tasks that emerge to be needed.
