Can I copy from a few different terms of service pages from competitors?

I'm working with little funds so hiring a lawyer isn't an option. I'm starting a website like gazelle.com, nextworth.com, etc. and I was wondering if I can just use their concepts and piece together a terms of service based of theirs? I need to make many of the same statements.

You can analyze their agreements to start create your own, but it's not recommended to simply copy-paste as they have different needs from yours.

I'd suggest looking at 500px Terms of Service page:
http://500px.com/terms Or, if you need a Privacy Policy too, have a look at LinkedIn's.

A free generator of Terms & Conditions agreements that you can use:

It's common practice, even for professional lawyers, to use a template when creating a new legal document. Using someone else's agreement as a template is acceptable.

If you do end up working with a lawyer later, they may want to throw away what you have and use their own template. Just be ready for that.

WordPress has explicitly open-sourced their terms of service and privacy policy, which is how we made ours:
