create a wordpress site with event expresso

I am a chiropractor and teacher. I run bodywork workshops and long courses. I want people to be able to book and pay online. I currently use business catalyst for my main website and eventbee plus paypal for booking events. I have two blogs running on [login to view URL] - I have found wordpress easy to use and spam free. I want to shift my main website from business catalyst (too expensive, loads of features I do not use, I get loads of spam clients I cannot seem to prevent, and limited blogging) to a wordpress site (.com or .org if needed???) integrating event expresso for the workshops I run. I would also like to shift away from paypal (they recently put a reserve on my account that annoys me to distraction) [login to view URL] is my main website and the next event I run is on http://trelondonleveltwo.eventbee.com. People get to this site via one of my wordpress blogs: [login to view URL] The longer courses I run are advertised on [login to view URL] There is a simple paypal button on this site - no booking features. Hope all that makes sense cheers Steve
