It depends on how much time you want to devote to it and the present level of knowledge you have. The fact that you're asking these questions is a good start, but suggests your level of knowledge is low.
Any website building is a learning curve. Whether you use Wordpress to build a site or Webplus X5 is of little relevance, though it's probably fair to say, Wordpress has a greater learning curve to make it do what you want. In my view, for a simple site, Wordpress is an overkill.
If you want to blog, then Wordpress is the better solution, but it worries me you said "If I get time in the future I may interact more & add the odd blog as I understand Google ratings like this". That is no way to start and suggests you are not serious at all about a web presence, but think it's something you should have. Blogging like that will have at best a zero effect on any rankings and could even actually have a negative effect, as the site will be seen as being abandoned.
Just be aware, an amateurish looking site that is business orientated, can do more harm than good. People mentally create expectations based on what they see and if your site doesn't look good or accurately portray your business, it's likely to turn people away and have a negative effect on your business and you're probably better off without it. You'll look like a cowboy and that's the perception people will form. Those people that have been put off, may have just picked up the phone to talk to you, but now won't bother.
To build a good site takes expertise, time and therefore money. You get what you pay for.
However, if you want to proceed, the very first thing you must do is find a domain name and register it. You can do that through 1and1, or my preference 123-reg or any number of other mainstream registrars.
