(this includes mastering, as I'm fairly sure most people dont read and will come back and ask the same question )
If you go to an independent specialist mastering studio you look in the region of around £220 to £250 inc vat for a 2 track vinyl master.
The cost of a pressing ( a run of finished vinyl) depends on the plant and if you go direct or through a broker. Through a broker is more expensive, but if it starts going wrong your not the one chasing your tail the broker is.
Distribution is generally best through a distributor, if you have a bit of a buzz and / or quality material most are willing to work with you, but do some background research, look at what other labels they distribute, what their coverage is.
Self distribute is a little easier now with things like big cartel (online shop) or you can trek round all the shops and try and get them to take them as SOR (sale or return) stock. Many of the now big labels started in this way.
other things to consider are, art work. making sure the tracks have been mixed properly for the format but mainly make sure the material is something you believe in and it is ok to be different
Hope that helps and clears things up
