You will occasionally come accross full set ups on ebay. Your budget is unlikely to get anything worth having but you may get lucky.
I would research a whole lot more, including searching through old posts on here. A good starting point once you have at least a theoretical understanding would be a basic training course, again, search on here.
You may then have an idea of what you need and can start shopping around.
Just to put things into perspective, a HWE machine alone will probably cost less than a third of your initial budget. The cost of accessories (essential and non), chemicals, marketing etc. soon add up and will cost £1000's in their own right.
If you are looking at a quick turnaround then I would steer clear. If you intend this as a long term add on, then devise a proper plan and work to it.
