You could start at a library near you that has a 3D printer, they can show you how to use it, print items for you etc, it may not be the best advice but it is a starting point. from there maybe a community based workshop (not sure what they are called over there, here they are Makerspace or a variation on). You probably get better advice from there.
I wont give you any advice about what is a good/bad printer, or software as there are probably thousands out there, and every one has its good and bad bits.
what I will tell you is the pit falls to look out for and that is lots of advice, most will be conflicting, a lot will be second hand info ( I have a friend of a friend who says).
and if I had to give you any advice it would be what I wrote above, go and find a place or someone that has a 3D printer and learn how to use it, pick their brain on pit falls of that style of product.
Hope that helps start your journey a little easier.

Andrew
