I also have/had an online  business for a few years and I have a decent amount of experience with wordpress blogs and online marketing/advertising on Facebook and I would like to use all of that as part of my strategy for finding deals too.

Hey @David Nichols, here are all the tips, ideas and suggestions you could ever ask for:https://www.biggerpockets.com/search/wordpress?

We do a number of different things so I built our site on Wordpress.  

Building the website can cost anywhere from $0 - $lots of thousands depending on who does it and what you are trying to accomplish.If you are going to build it yourself, I recommend a free CMS (like WordPress) because there are MILLIONS of videos and tutorials, templates, and other resources.

You could do a WordPress website,I've built my own for my business. 

My current plan is to put together a quick simple wordpress website to help me gain leads.

Wordpress has simple themes like this that are free, and the forms also integrate just fine with tools like Zapier.

You can add various plug in’s to cover the booking and calendar.You could build on the Wordpress platform.

I am interested in SEO, Websites like Lead Propeller, Investor Carrot, or Doing it myself (I have an IT Background and done my own Word Press Site before), Facebook and Instagram Marketing, Google Pay Per Click, and Email Campaigns. 

I believe it's instant, but don't quote me on that.2) Yes - they have a website builder (which I don't use) and also a widget that you can embed into a website (I use this on my wordpress site).
