I would like some guidance in developing a valuation model for the below question feel free to use other numbers and such. I will not use your work as mine I am trying to understand the valuation model.

Develop and present a valuation model for corporate debt with a face value of $70 million dollars. The model should use hypothetical assumptions for the coupon rate and other characteristics as well as a hypothetical market interest rate. You must also select a maturity for the bonds and the frequency of the coupon payments. The market rate should be justifiable/reasonable given current market conditions. Explain why the model will be important for the issuance process that is being considered.
