Welcome along to the forums. There are lots of active members around Kent and plenty of stuff to keep you busy.
Why not share some reports of your permission visits you can arrange? Or share some of your research in the 'leads and rumours' section?
Id recommend doing this to show you have a genuine interest and will do the leg-work before asking people to explore with you. There are too many new members joining here looking to be taken places and get a free-ride and as such this sort of post will generally get little to no response.
Sadly alas I would but looking for someone to come with me as I have to dodgey knees and need someone with me I can arrange places with abandoned trains, also a house I know the locations and willing to take people just can't go alone
