First of all. A LARGE CONTRACT WITH NO KNOWLEDGE!! Sounds like a disaster to me.
The best machine?? We all have our preferences so you could get 10 different answers. I know it's no help but it's the truth..
Also, having the best equipment is not going to make you an expert, EXPERTS in this game have been in it for a long time and have vast amounts of training and on the job experience.
You need to get some training. My suggestion would be a course AND on the job training with one of the experienced guys about 20-30 miles from you!!
Hope this helps!!
