When we made the choice to have me stay home I did something kind of different --- I found ways to make the income we did have go further. I made my "job" finding deals, creating a budget, cutting expenses. You can make money simply by freeing up the money you're currently using. I tell my friends I make my husbands $1 spend like a $1.50.
I plan grocery shops based on the current ads. Cut out impulse buys -- no random trips to Wal-Mart or Target. I cancelled Cable/SatelliteTV - so we just have internet. Get Netflix instead of Cable and buying movies. Put up an antenna to get local HD channels free. That saved me $60-$100 a month. If you have a house line switch to Ooma - its just like Vonage but much cheaper. Basic service is just your local taxes.. generally about $4 a month. Doing this saved me $40 a month. . Cook instead of eating out. Clip coupons. Stock up when there is a good sale on stuff we use all the time (Toilet paper, laundry detergent). I *never* pay retail. You wouldn't believe the deals I find. My friends always come to me when they are looking for something. I buy clothes for my husband and kids from Kohls - clearance/sales plus 30% off.. most of the time I pay 1-2 dollars for a brand new shirt. I shop at TJ Maxx/Marshalls as well. My sons $40 Robeez were $15. It all adds up. Doing this we were able to adjust to going to nearly half our income.
Sit down and look at your bank statement. You might be amazed to see where your money is going. We were eating out and I knew we needed to cut back... but we were spending at least 2-3x what I thought on FOOD between groceries and eating out.
You can also order food from http://www.angelfoodministries.com/ to save even MORE on your budget.
My friend donates plasma for money hehe. You can go more often then blood (weekly I want to say) and she gets $75 each time. She very quickly made her entire Christmas budget. :)
Get creative and I bet you can do it.
