If you feel that you are not capable of creating a speech, then I have some advice that I would like to offer you.  My parents decided to renew their vows, and the groom speech that my dad gave was just incredible.  I asked him about it and he told me that he had a professional write it for him, but he did give a lot of his own input.  I am shocked that my dad went through all that trouble, but I feel that it was completely worth it.  I think other people should consider what he did for their own personal use.
