Clonaid.com can help you if you want an 'identical twin'

If you’ve just lost, or are about to lose, a beloved family member, and would like to see an 'identical twin' of that person begin a new life, then maybe Clonaid.com can help you.
Identical twins are 'monozygotic', that is, they develop from a single, fertilized egg that later split. Of course, a clone of your loved one shouldn't strictly be called a twin, because twins are the result of one pregnancy, whereas a clone would involve a second pregnancy. Source
