Looking for a double room

I’m a hard working individual who is currently training in the armed forces. Due to this my official employment start date within the army will be September 1st.
I am finding it hard to locate a landlord who understands that part of my career includes unpaid training (9months) the council will be paying full months rent including a deposit upfront for me to secure a place. I have all documentation to support my career I just need help finding a place in the meantime who can accept this. I’m looking for a double room in or around Maidstone town centre.
