it is a DIY job if you have time, money and some know how. Ideally, u should get the parts yourself and then give it all to someone else to assemble and setup. That's my opinion of what you "should" do. However i would try and do it myself then give it to someone with the equipment and skill to set it up fuelling etc. Whatever you feel your up to i suppose, many people have built themselves ZTs and the pool of knowledge is huge in the area which is always helpful. I'm rambling.
