WordPress Crowdfunding

It depends on your (or your resources) coding skills. If lacking, coding skill can be hired – try jobs.wordpress.net.

With adequate skills acquired you can either develop from scratch a bespoke plugin that does exactly what you want. Or if there’s an existing plugin that’s close, you could simply adapt it to your needs. This can even be done with commercial for-pay plugins as long as their code is not obfuscated.

Ideally you would adapt plugins by hooking into provided actions or filters, or by adapting pluggable functions. Done this way, your custom work is not overwritten by plugin updates.

If your choice plugin does not offer the desired hooks, you can still adapt it by directly editing the plugin files, but then you’ve essentially voided all implied warranty and support, and you’ll need to reapply your changes after updates, or forgo updates and assume responsibility for any security risks that may exist.
