but I would be selling this personally

Given the evaluation, I have to assume:
1) that the site is making decent money already,
2) that you are reporting that income to the appropriate tax authorities, and
3) that the tax authorities consider your site some sort of business entity.
In you're in the U.S., if the site/business is "personal" (and not some sort of separate legal entity like an LLC, corporation, partnership, etc.), you'd report the income/expenses on Schedule C on your 1040 personal tax return.

Besides a broker, you should also strongly consider talking to your tax preparer and/or a lawyer to make sure things are setup on your side to minimize the tax hit if/when the sale goes through.
