Hi Geraldo22,
If you can't find a speech therapist locally, I can offer you an online service. It is like face-to-face, but I speak to you over clear line (like Skype), I present pictures etc on the screen and you see them. We then work though a series of speech therapy exercises and I email any information or exercises you need. I am a qualified speech therapist and have conducted lisp speech sessions online before. Online sessions are usually cheaper as well. Have a look at my Online Therapy page on the icommunicate website. Let me know if you are interested.
