We have some improvements planned to simplify creating packages, it can definitely be a little confusing your first time through.
You have probably done most of it right, and Mike's tutorial on the Universal Module is good.
Any packages you have that you don't want to use, just change them to inactive and create a new one. Here's the basic order for using the Universal Module and creating a package.
Create a Universal Module product. If the customer should be presented to fill out anything for the service, create 1 or more service fields. Settings > Company > Modules > Universal Module
Create a Package, select the Universal Module as the module, and the Product you created above.
Set your pricing and other options
Add this package to an existing Package Group, or create a new group from here.
If you are adding the services to clients manually, you can use the Add Service option on their profile page, select the package, and continue through the wizard to add the service. If you want customers to be able to order the package directly, create an order form under Packages > Order Forms and add the Package Group to the order form.
If you want a little help getting this initial one set up, you're welcome to give me a call at 714-398-8132 x100. We're in the USA.
