Need Help writing SNORT Rules for the following I've never done this before

I need some help in writing snort rules for the following, I have never done this before, can someone please help me. Thanks 1. (1 point) Write a Snort rule that will alert on TCP traffic exiting the 10.0.1.0/24 network with the content "proprietary". I do not care where the traffic is going or what ports it is using. When Snort creates the alert it should read "Proprietary information leaving!" 2. (1 point) Write a Snort rule that will log any TCP traffic entering into the 192.168.100.0/24 and 10.2.2.0/24 networks with destination ports 1 through 1024. I do not care about the source IP addresses or source ports. When Snort logs the traffic it should read "Incoming to low ports". 3. (1 point) Write a Snort rule that will alert on UDP traffic entering the 192.168.10.0/24 network that contains the content "cgi-bin" anywhere between the 5th byte offset to the 25th byte offset. The alert should trigger on both lowercase and uppercase content. I do not care about the source ports or destination ports. When Snort creates the alert it should read "UDP CGI exploit".
