Shortening a bed?

I have a very awkward room where I need to fit a small double bed but it is about 5cm short of space for me to put it the way I want to go. And taking off skirting would not help as it is the wall issue. 190 long matters will fit as it will squash a bit but not a 190cm bed frame, need to have 185cm (max) frame but to be safe 180cm would be best. Had a Jay double folding bed in that space with a normal size mattress on top and it was fine as a temporary measure

I have searched for shorter beds but they are usually kids beds (ie single) so not what I need or completely ugly things...

Is there anywhere locally that someone knows of that I can have a bed shortened?

Or a carpenter who could do this kind of adjustment?

Any idea how much would that cost?

Planning to get the bed in July....

Thanks a lot
