Hi Albert,
Why don't you group your classes by domain (all services and models related to one domain go in one package) rather than by functionality (group all models together, group all services together)? This way you can use package-private constructors. Plus it will be easier and more logical for your readers to find the classes you are referring in your services and you can reduce the size of your imports. Also, if ChildClass1 and ChildClass2 are pojos, which seems likely given your structure, you can simply use "new" instead of going through a factory. Using Guice for Pojos is like using a bazooka to kill fly when good old fashioned tools still do the job properly.
