Help with understanding

Hi, I am a PHP developer. I have used WordPress but I have never delved into the templates or the code behind it.

I don’t know if this is common place, but this is what I would like to do, and I wanted to see if this has been done before and how to approach it.

My customer runs a repair company, so he requires the basic pages of a website – e.g. home page, about us, testimonials, etc etc. But then for each unit that he repairs he has another page, then for each repair of each unit we have another page. I run this on the current websites using PHP and parameters, and now I have started using .htaccess to get more useful URLs e.g. repaircentre.com/apple/iphone-4/broken-screen

So my question is how to approach this but using wordpress to manage the static pages (we already have backend systems to manage the models and repair pricing).

It might be straightforward, but I don’t seem to be able to get my head around it!

Any insight would be much appreciated!
