It would be my highest recommendation for you to buy a tool that automates the tasks which you are already doing manually yourself as most of the tools represent techniques that you can do on your own.
That is basically how I run my business we typically purchase tools to automate the tasks which we are already doing ourselves and if we are unable to find one we build it ourselves.
I believe that many people have this fantasy that purchasing a tool magically create a flood of traffic without any knowledge or effort needed unfortunately this is not reality.
So my suggestion is to first practice different techniques and methodologies and see which ones are working for you. After you found a method that seems to be working quite well compared to the rest that are within your test group then try to simplify the method by purchasing a tool which supports the activities.
