Weddingbee boards

I have been engaged for quite awhile now but have refused to get married without my sister by my side.  She has been in federal prison for a little over three years and will be in a halfway house November 2010.  I was hoping to finally set my date, but not knowing if she can attend my wedding in a halfway house and if she'll even be in the halfway house for the full 6 months is causing me more problems.  I have been engaged, like I said, for years and am so eager to make it official.  I know what dress I desperately want, but have yet to actually go buy it because of the unknown date.  Since getting engaged I have gained considerable weight but I bought an exercise bike and am ready to get things rolling!  I had to put off finishing college to help take care of my sisters two boys and so my fiancee and I do not have a lot of money.  We want an intimate (30 or so) person wedding.  We are now looking to marry hopefully in March 2011.  We literally cannot spend more than $3000 on the entire wedding/honey moon.  Any ideas?  We want our colors to be black and green or tan and green.  Planning on doing lots of DIY!  I need help finding caterers and a great reception site.  We are also doing a nondenominational wedding since we are jewish and christian.  I was thinking St. Mary's Chapel for the ceremony.  So if you have any ideas or heck, if you know anything about Charlotte Halfway houses, let me know!
