I need help in finance but don't want to post all the questions. I am looking for someone I can work with directly. here is a sample of a question

An individual created a new financial app that is called Smartstrap. This instrument gives the holder access to the following cash flows:

• For the first 4 years, the holder receives $75 per year starting one year from today (a total of 4 payments).
• The holder does not receive any cashflows for year 5.
• Starting at the end of year 6, the holder receives $50 growing at a rate of 5% per year forever.
• The holder has to pay a service fee of $9 every year starting at the end of year 2; this goes on forever.

The prevailing discount rate throughout is 6%. The individual would like to determine a fair market price for this app, what do you think the price should be?
