Don't matter if you want to be serious, funny, make people cry or laugh, or whatever emotions you want to cause on your cousin, family and friends, I'll do it for you! My former expertise (in business) provided me the necessary experience and skills to impact the life of my customers, employees and general public in a positive way for lots of times.
And these are the skills which are going to make your speech a GREAT AND SPECIAL MOMENT with your family and friends, and a memorable time to your cousin and his/her wife!
PS: I might review the days to delivery if it's urgent, so you get all this in time.
