Hi,
Like you, I am also a self taught freelancer. While I am not too sure what exactly you have in mind by 'teaching', what I am thinking of is providing you links to study and handling any doubts/queries you have in mind.
Since these tasks are generally done over a long period of time, I am willing to do an extended project with you.
We could start with maybe creating your own profile page(using javascript, HTML and CSS) and then add a contact-me form based on PHP or we could create a cart and checkout system for a basic ecommerce website.
These will teach you all the things you need.
The bid I have placed above is tentative and it will depend upon the kind of support you're looking for. Message me and we can discuss the proper details.
Regards,
Sudhanshu
