On your search screen, click on the name of the player you're trying to recruit -- this will bring up his player card. On that card, there's a recruiting tab that you can click and which should bring up all the list of options as well as their cost.
If the only option you're seeing is to place the player on your watch list, you'll need to clear the browser cache, clear cookies and restart your computer. Following these directions a second time should get you to the recruiting options.
