This is the standard wiring diagram for a system like this.  You can
clearly see that it is composed three distinct items:

1.  The heater (box and heating elements)

2.  The controller (including one or more temperature sensors)

3.  A solid-state relay.

It is difficult to tell if you are asking for someone to provide all
three parts or just the controller.

I will point out that the heater itself at the size you are asking
will almost certainly represent the greatest cost of materials unless
they can be sourced from scrap.  I imagine that the cost of shipping
such a device could approach (or even exceed) the cost of materials.

There is a fourth item somewhat hidden in here:  The software that
allows the user to develop the temperature profile.  Implementing a
PID loop to maintain a constant temperature on a microcontroller is a
trivial task.  Developing software which will allow the user to edit a
temperature profile is very much a non-trivial task.
