When it comes down to the investment Bill, given you can only produce 1- and 2-layer boards with no silkscreen, I don't think it's worth making home PCBs. I'm lucky enough to have been given a 4 lamp timed UV exposure unit (approx value £200) and was actually considering manufacturing some boards at home, but given you can get them done for maybe £40 each it's not really worth it.There is one level simpler, also more prone to errors, hand draw your layout on a piece of copper board with a sharpie (an American brand of magic marker that comes in several widths). Basically it needs to be water proof.
Etchants are not too hard to find, there are several different kinds, some you can make with hydrogen peroxide and Muriatic Acid, which are available from pharmacies and hardware stores (the latter being a swimming pool chemical, basically hydrochloric acid). You will need good latex gloves, a deep glass dish, and some simple tools (wooden dowels come to mind, they will be destroyed long term).
One of our members here on AAC (Tom Goottee) has an excellent website for how to DIY. It is possible to use a laser printer (not an ink jet) to make high quality printed circuit boards. He also describes how to etch a board that has been prepared.

You can choose a few online quote and order manufacturers. the quality is very good and low cost.For Example: PCBwing.com , You should try it.
If your PCB is very small size, you should try BatchPCB.com group purchase.
