How can I add a field in the contact form

Hello,

My boss asked I insert new field in form that is in the module at the left. But I can't find the way to do. Could you give me an advice?

Besides, Hot Effects Rotator and BIG TEXT are very very near. How could I make the distance between them bigger?

I hope you could help me. (You always do!

Thanks in advance

My site is in cpcmetepec.com.mx/pruebas/
