We all know that for most people access to space is currently pretty limited because space flight services are expensive, as they are in short supply.
Suppose I wanted to bypass an expensive service and get into space as quickly as possible. Could I build a suborbital spaceflight vehicle in my backyard with components that an individual could get access to?
If the components are easy enough to access, but the number of people doing the construction is a limiting factor--could I do it with 5? 10? Any number less than 100 (at which point the line between an organization and a DIY effort is blurry)?
If it is possible to get the components and construct the vehicle with a few people, would it be possible for this small effort to control the construction enough to keep the risk factor manageable?
Would there be any legal considerations?

Note: I'm not asking if this could be done on the ordinary man's budget. Supposing the average person could get access to all the money that they needed to get it done, could they do it themselves or with a small group of people? The answer should still mention the cost, however; as it is an important practical determiner of whether or not it will actually be done.
