In addition to the offer through John Stevenson's excellent site, it is quite possible to do the ends of mills with fairly basic homemade tooling.
I can pass some information if you will e-mail me giving you proper E-mail add.
However, if you have things like collets and dividing heads or whatever, you should be able to do mills and tools and so forth without undue bother.
All that you are doing is to create a cutting edge and secondary relief angle on perhaps two lips in much the same way as Pete has demonstrated in another post -on which I praised.
