I’m an attorney, and just for clarification, most legal internships are unpaid. You may be able to get an intership that is paid, but just like any other industry interns usually work for free.

Since you have not attended law school, I do not believe that your level of “legal knowledge” is a requisite. If I were you I would emphasize my interest in pursuing a career in the law and your aptitude to learn things quickly and apply yourself to a task. Also, if you have superior computer skills (based on your internet company) I’d emphasize that. Most lawyers are Neanderthals when it comes to technology and if you can make that portion of their life easier, then better for you.

Also, don’t feel pressured to have worked in a law firm prior to law school. Before I entered law school I hadn’t set foot in a law firm or government legal agency. I don’t believe that working in a law firm will make you anymore successful in law school because as any practioner knows, practicing law and law school curriculas are too totally different beasts.

Also, be aware that if you are applying to intern in a big law firm, you are also competing with other law students. I would suggest that you contact government agencies like the public defender, prosecutor’s office, or attorney general’s office as a possible source for internships. Although, you may be in competition for a spot in these agencies, there may be more room for you.

I hope my advice helps.
