@mlefu - I have good and bad news for you.
Bad news: There are very many ladies out there looking for a man to father a baby for them - but they get to keep the baby.
Good news: If you know any lady who is looking for a man to father her kids, then you can come to some sort of arrangement. Either you get kids together and you are grated visitation rights - this is not the best because you are family that lives apart no matter how you look at it. I gather that you don't want a lady as part of your life so this might not work out nicely unless meticulously planned. Second option is that you get two kids [or multiples of two] - one for you and one for her. But you have to take the first one otherwise chances of her seeing out her end of the deal will be lowered. The problem is, wont you feel guilty keeping a kid away from her brother or sister? Will they eventually meet? At what age? How do you explain to them how it all happened?
Another option: Rent a womb. It's big business in India! But you need someone to donate the 'egg'. This might be easier to find than a lady who will carry a baby for nine months, hand her/him to you after hours/days of labour and say goodbye. Tafuta donor, enough funds for round trip tickets for two to Idia and the procedure, pesa ya 'rent', then we will talk. In the mean time, visit the following links:

Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
