NEED SOME ADVICE

Hi, I’ve just bought a ford transit connect 2006, 

any suggestions on set ups and gear for me, I’ll be going DIY because everyone I spoke to said it’s better than getting a professional system

It's not 'better' it's cheaper.  As long as it's cleaning windows that's what matters. 

If you're competent you can save plenty with D.I.Y. 

What you now need to do is look through all the suppliers their offerings and see which parts best suit your budget and requirements. 

There are loads of threads in the DIY section on self builds so have a browse through there and see what you like.
