I recommend the things that I use and have had success with.  You need some tools for sure to build your online marketing hub.

Education and Training – This is really the absolute first step you will need in beginning your online marketing journey.  You will need to learn, study and apply.  Join Marketing Merge and gain an extraordinary education for a small investment.  If you have a low budget, Start Here at Renegade University.

Blog – Use WordPress.org  This software is free, but you will have to buy a domain name and have it hosted.

Hosting – You will have to host your WordPress.org site with a compatible host.  If you visit WordPress.org, they will make recommendations.  I am using BlueHost for the hosting of my website.   After checking around, I found that BlueHost had the best prices.

Domains – I have used Go Daddy and ePresenceSolutions for my domains.  ePresence is a little less expensive.

Autoresponders – I use Aweber.  They can't be beat in terms of functionality, pricing, and assistance.  They will bend over backwards to help you.  

Health – Need more energy? Here's what I use to boost my immune system, gain energy and alleviate minor aches and pains!  I'm not kidding.  It's the best!  (I am not building a business with this; I just love the product.)
