100% agree with ainsej. Do not waste money on any paid advertising without a proper landing page/website set up. The way your site is now, there is no way you'd get anyone to convert, so you'd just be throwing money away on those clicks. The only people who may sign up are those looking to spam, attack, dos, or abuse your services in one way or another.

The $350 for attorney to review your ToS is not the right way to use your funds. You can find some decent templates for ToS or borrow from other hosts and edit/rewrite portions yourself. You need to solidify your product and overall brand/appearance before you spend any money on marketing and legal.
