Torsion Spring Calculations

Job ID: 31332872

Budget: $30 – $250 USD

I need 2 torsion springs that together can lift a weight of 40 lbs at a distance of 14 inches.
The compression angle should be 45 degrees after the weight is loaded. I am hoping that the total force per degree doesn’t exceed 2 kg or is very close to it.
How much would it cost to calculate the dimensions of such a torsion spring? I am interested in wire diameter, amount of coils, coil diameter etc.
What is the spring rate? How much additional force needs to be applied to push the weight down further? Also please suggest if such a torsion spring is even viable or can exist.

I appreciate your quote and answer. Thank you.
