DNN real estate site driving me crazy

[b00m3r]

Man, I'm just hoping somebody out there hears me and throws me a bone. I'm trying, more like beating my head against hard and soft things alike, to optimize a website I manage for SEO. It is a real estate website on DNN and uses an IDX solution for MLS home listings, creating searches and maps for pages, etc. It is a new domain (a few months with an expiration in 10 years I believe) in a an extremely competitive market with very little inbound links which I am slowly but surely building. I recently have helped on two other sites that are brand new and are already ranking extremely well for targeted keywords. I'm doing everything I can but the search engines are acting like this site has the plague. Can anybody give me any advice as to what could possibly going on? Is it the IDX solution? Is it just too new for such a competitive market? Or is it just jacked all the way around? Please help. The website is www.homesforsalenorthtexas.com. Any advice or comments are EXTREMELY welcome. Thanks.

Keep the site as it is because it is simply the best. I must say I am really pleased to see such site which sharing good knowledge.Colour combination of background and font I like most. Speed of response also the best.
