Thinking of signing up my single uncle for a matchmaker company.

My uncle has been single for nearly seven years now, following my aunt's death to a car accident. Since then, he hasn't really expressed any interest in dating or getting married again, and I'm a little worried that he won't have anyone to spend the rest of his later years with. To help set him up with other single ladies, I was thinking of signing him up with a foreign affair matchmaker company. To help convince my uncle, I was hoping some of you guys could share your stories or positive experiences with the same company since I haven't tried it before. Thanks in advance!
