It's very hard for me to just pull sentences out of air.... please give me some idea of what kind of sentences you'd like, or at least a general topic.... ^-^*
So, if you please give me an idea, I'd love to give you some sentences...
Tae Kim's Grammar Guide has lots of example sentences.... (and, if you hover over the kanji, you get the reading, and the meaning!)
This has some sentences with translation.. (if you don't understand any of the words, let me know)... http://www.linguanaut.com/english_japanese.htm
Also, juts looking at song lyrics with translations helps... (animelyrics.com usually has good translations... and, sometimes, kanji lyrics, too).
This site has grammar stuff, and I think it's helpful (I wish I had found it when I was just learning.... ^-^) http://kimallen.sheepdogdesign.net/Japanese/index.html
Here's another good beginner site: http://japanese.about.com/blintroductory.htm
Anyhow, if you have any questions, please let me know.... I'd love to help... I'm just not very creative with making sentences (plus, I don't know what forms would be most helpful for you...)
