Looking at the size of your herb bed, I wouldn't plant either rosemary or mint in there, or you won't have room for anything else within a couple of seasons!!
I bought a TINY rosemary plant from B & Q about nine years ago and planted it in my front garden - within five years it was five feet high and had spread about four feet! Admittedly, we live(d) on the cliffs - sandy soil, sun, wind - it probably felt right at home - but I think it would take over your herb bed!
I'd be happy to send you some seeds to get you started - I have basil, coriander, parsley, oregano, mint (if you grow it in a pot), chives, marjoram, sage and thyme. PM me your address and what you want.
Incidentally, for the mint, it's quicker just to pinch a bit (who said that???!!!!!) from an established plant and stand it in a jar of water - when roots start growing out the sides, bung it in a pot of earth. I've even done this with those "growing" herbs you get from the supermarket (ones I've bought, obviously, I don't advocate pinching bits from plants in shops!!!!!).
Homebase also do packs of say six plants, and they often seem to mark them down quite drastically, for example if one or more of the plants is looking a bit manky. If you go through all the packs on a shelf, you can often find a pack which is still pretty good, often at more-or-less no money.
