Moodle has pointed the way to the Moodle Exchange. There the backups for courses, quizzes, glossaries, scorm resources and other things can be shared. Some of my courses are there if you want to take a look. You are free to use them if you would like. There is also a forum where people have begun posting websites that have Moodle based classes to share. I hope some of your teachers will want to share.
In my district Moodle site, I have a category for "Demos and templates" where we have posted some thematic units built in Moodle. Teachers can look these over and see how they are organized. They can use them just to get ideas or request a course copy. I can use a course backup to make a "copy" (using restore feature) of the entire course for them that they can then modify to their own use. The other option is to "import" the resources, assignments, etc. from the original course into their course. Everything comes into the topic area they were located in in the original course and may need to be rearranged.
This is one of the advantages of Moodle that are often overlooked. It is one of the most powerful advantage because teachers don't all have to make up the courses from scratch but can still have the freedom to make it their own and change over time.
One example (which you may want to use with your teachers) is a Biome project I created as a sample. I had the students using a Wiki to gather information to share in their groups and doing a PowerPoint at the end of the unit. A high school teacher used my class but decided to use a database for the students to post their infomation to share and have them do a digital movie at the end of the unit. She hid the options she didn't use when she created her own... that way she can go back to them another year if she wishes.
