Wow, why shouting?

To answer one important question. Yes, you can farm out the manufactoring of components.
Many of us learned the hard way, even if the initial pricetag can/will be steep, the benefits are proportional.

A few roboteers do make or sell parts. Some for the challenge, others to pay for the tools and new robots they build. You'll find them on the forum.

Best start is to read the build diaries on this forum, come to live events, talk to the roboteers.
Surpising low numbers of obnoxious or arrogant of people doing Robot Wars.
