Side income blog

My hubby is working hard to promote my Kids Islands blog now. He wishes I can do it full time very soon. If possible, by early next year! He is seriously promoting my handmade online store, no joke. Now most of my sales are brought back by him, frankly I don't know how he make it.
I ever suggested to him using directory submission to promote the link. And he did agree with me too. But using this service might need to pay certain fee...hehe...I wonder will he agree to pay or not?
