Keyword research doesn't need lots of technical knowledge just think like a visitor and you will automatically come to know about it. While there are some tools are available there, creativity is what that keeps you ahead and distinct from others. SEO is not just what that you can do with automatic tools it needs innovative ideas as everyone else would be following the same things that are easily available on search engines. Think seriously about the services you are offering. If the services are localized add the name of that particular locality along with your services. Talk with some real time audience and find out what most people like to input in search engines while searching the particular services you are offering. Once you find out the most preferred main keyword you can use automatic keyword research tools but before that it is good for nothing.
Google's Keyword research tool is the best and freely available tool for doing Keywoord research once you master that you can move on paid tools like overture etc.
Use Google's keyword tool to generate the biggest list you can for your keyword, use very broad keywords when building your list and filter it down from there. In other words don't use long tail keywords to try and build the list (eg. use "dogs", and not "dog training texas") Determine if there's enough traffic using exact match. Also see if the CPC is high enough, not so much for Adsense, but to see if it's a profitable keyword. When you've found some keywords use MarketSamurai or TrafficTravis (SEO competition module) to determine the strength of the first page in the SERPs.
