If all you want to do is incorporate and you are going to be the sole shareholder, you can do it via an Internet service. Lawyers are useful if you need anything more complex than this e.g., agreements for the initial shareholders, stock options agreements, etc.

If all you're doing is creating a corporation for legal protection, then do it yourself.

One word of advice though, think through how many shares you want to issue. If you're going to offer stock options, then issue a huge number - like 10 million. If you don't think you'll need options, then go for just a few.

If you pick too few now, you'll need to hire a laywer in the future to help you with a stock split or share issue to increase the number of shares.

Also, one other word: if you're just incorporating for yourself and don't plan on getting any venture funding in the foreseeable future, incorporate as an LLC so you can pass the tax losses from your company on to your personal taxes.
