Hello
Ah well, I'm a fair bit older than you, maybe it might be best if I explained how things work if you are interested in doing Archaeology as a career nowadays.
There are two real routes into Archaeology. You can go to University and get an Archaeology degree and then maybe specialise ( I specialise in natural fibres and textile production, a fair bit of traditonal plant uses and some of the medicines of the past), or you can become a member of the Council of Field Archaeologists and then you mostly end up working on contract to Archaeology Services.
Often the field archaeologists are incredibly capable and knowledgeable because they have built up a huge wealth of experience.
My message is too long so I've split it here
