To be clear: are you looking for help cutting an existing file/design, or help with the design process AND the cutout?
The latter calls for a much higher level of commitment.
If you don’t get any takers for the CNC and have measured drawings (but not necessarily a VCarve Design file), I’d be glad to help you cut it out using the table saw and band saw.
You’d probably need a saber saw (get new blades for DMS saw, just in case) and an appropriately-sized hole sale (likely NOT already at DMS, but cheap from Home Depot) to cut out the ladder rungs.
You would also need some 2x2 stock (perhaps) to reinforce the corner attachments and make the mattress support, screws/bolts, etc.
I am usually at the DMS from 7pm til midnight or later on Thursdays, and will be on 3/30. I could perhaps be available on another day, with notice (35 mile 1-way drive for me limits my visits).
