Hi - I have the starter plan for our non profit which has worked great for us for a few years.  We are not hosting events and I would like to be able to either offer a link for our pottential vendors - a link to a downloadable PDF agreement or to Google Docs downloadable agreements -- or to square order form.. or even Eventbrite.  How can I do this?  Can someone please help me...  Do I have to upgrade?  and if so to which version?

PS:  I am doing the website on my own... I don't have a web person.. so I am trying to do this without having to hire a webmaster.  Thanks!!!
