Hi,
It certainly is interesting, we really have no idea what is lying there under the soil, as the Staffordhire Hoard alone proved.
What happens to items found? Well, anything classed as treasure (which very broadly speaking are items over 300 years old ) . Here's some links with more info

I would adhere strictly to the law, documenting finds etc. Every little artefact found is another piece to the jigsaw puzzle of the past.
Anything classed as treasure and subsequently sold ( usually to museums) , profit would be split 50/50 between us. We would both sign an agreement such as this one http://www.detecnicks.co.uk/agreement-with-farmer.pdf before any detecting takes place . I would also adhere to all request re boundaries, allowed fields etc.
Everything else of interest? Well, as the landowner you would get first refusal on the other items found. It's inevitable that within 180 acres there would be many weird and wonderful objects....and treasure?...who knows :) You could have a little display cabinet full of stuff!
Any junk ( and there'd be plenty) would be bagged and removed , there would be no point throwing away a shotgun cartridge to the side only to detect it again a few weeks later.
I could go on but i won't bore you. needless to say if you would like to discuss further then please email me at adrianfinegan@googlemail.com or call me on 07931401130.
BTW in the meantime, if you've noticed any shells, old pottery, discolouration in soil from one place to another then these could be signs of an old settlement = people = great potential.
Worth bearing in mind when out and about.
Be great to hear from you.
Kind Regards,
Adrian
