Depends on how interrested u are in game shooting? Can be a lot off work nvloved and depends wot sort of scale ur thinking about too.
If u are keen u could probably start up a wee syndicate but a lot will depend on ur ground. Is it dead flat or have small valleys u could fly birds across with guns in the bottoms?
If u are prepared to plant some cover crops as well would be a big benefit and make it more appealing as a shoot.
Are u in any HLS type environmental schemes as maybe grants/subsidies available for various different things from beetle banks, new hedges/woods, even supplementry feeding and even some cover crops depending on the mixes which all could help ur shoot and make ur land more appealing for nature in general
U could also just employ a land agent to value it and let it out to a shooting tennant (if ur not really that bothered about shooting) u will get an anual rent every year possibly plus a extras for cover crops etc.
Bear in mind the shooting tennant will need access over ur land esp from july/aug time onwards, not uncommon for farmers and keepers to be at loggerheads over acces (usually more with tennant farmers thou)
Probably an impossible question to properly answer over the net not knowing the area or ur farm, but it is a big enough area to do something with if u wanted too and the ground/terrain suits, but probably better to get some out to have a quick look over it and give u an opinion
