It sounds like you need to hire a developer. You might find some boilerplate or example code at

Some other resources are linked here (but may be out of date):

If you want to understand what you're doing, there's no substitute for doing it yourself.

There are some tools in the marketplace that can help you get started such as @ramonleenders Block Designer and Package Designer addons, which are for creating block and package code, and my own Package Magic addons, which are for zipping up, validating and deploying packages.

The use of these is not specific to the concrete5 marketplace. Many developers and agencies manage project specific packages outside of the marketplace.
