For getting cds on a budget remember that used is times again cheaper! Try putting up a want ad on your local freecycle group www.freecycle.org. Diaperswappers a has a free for shipping forum- http://www.diaperswappers.com/forum/forumdisplay.php?f=46 you can check out. You can find lots of great diapers used off www.diaperswappers.com, www.diaperpin.com and in our group through the Cloth Diaper Market forum.
Also buying seconds is also much cheaper then first qulity new. Seconds are new diapers that have some sort of flaw, normally cosmetic. Check on manufacture sites for their seconds, such as http://www.swaddlebees.com/Clearance. There are some good prices athttp://www.clothdiaperclearance.com/, they aren't as good as used, but they are better then other new sites, they are kinda hit and miss what they have in stock too.
If you can sew you can use old materials you already have and patterns found on line to make wonderful diapers.
And if you don't sew you can still use t-shirts you already have or buy cheap cheap at yard sales/thrift shops as cloth diapers with no sewing at all, see how here- http://www.cloth-diapers-made-easy.com/the-no-sew-tshirt-diaper.html.
