Suggest a Prusa Mk2 hotbed as the design will perfectly support that build dimension.
Aftermarket stepper kits are also available which fit perfectly. https://www.aliexpress.com/item/Reprap-Prusa-i3-MK2-MK2S-3d-printer-42-stepper-motor-320m-L-Z-Motor-with-Trapezoidal/32841178172.html
You may have better luck finding a stepper kit that is more affordable in your area or ones who's Z use couplers rather than direct connect Lead Screws.
