1) Online dating-- make it clear what you are looking for and be 100% honest about age, weight, height, etc. By putting the specifics out there, you have a chance to attract a woman. And answer their profiles, but be aware women are inundated by responses when it comes to online dating.
2) Get out in public and meet people. Female people, male people, married and single, etc. Someone who doesn't meet your specifications might know someone who does.
With both, keep an open mind and be patient.
