need quick fix classified script - easy job!

I need several things done. my site is at www.everylist.com. I need to fix some bugs, and change the way people post ads. Here is what I need: (1) - Need to fix a bug: "Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/every55/public_html/[login to view URL] on line 124" (2) - I need to change the posting feature. Currently, when users click on post, they have to choose a category. I want to remove this feature, so that when users click on a post, it will just take them straight to the post page. (3) - also, I need to change the post page to a different layout. Nothing really new, just changing the layout. See my attachment I included with this auction. This is a pretty easy job. $35 and no higher. Must have google talk. again, my site is at www.everylist.com.
