My problem is as follow:

Vorteck Inc.manufactures snowsuits. Vorteck is considering purchasing a new sewing machine at a cost of $2.5 million. Its existing machine was purchased five years ago at a price of $1.8 million; six months ago, Vorteck spent $55,000 to keep it operational. The existing sewing machine can be sold today for $260,000. The new sewing machine would require a one-time, $85,000 training cost. Operating costs would decrease by the following amounts for years 1 to 7: Year 1 $390,000 2 400,000 3 411,000 4 426,000 5 434,000 6 435,000 7 436,000 The new sewing machine would be depreciated according to the declining-balance method at a rate of 20%. The salvage value is expected to be $380,000. This new equipment would require maintenance costs of $95,000 at the end of the fifth year. The cost of capital is 9%. Instructions Calculate the net present value. (If net present value is negative enter with either a (-) sign preceding the number or (parenthesis) around the number. Round computations and final answer for present value to 0 decimal places, e.g. 125. Round computations for Discount Factor to 5 decimal places.) $ Should Vorteck purchase the new machine to replace the existing machine?

I thought I had this all figured out but I don't. I was going to use

and add the cash flow amount on the top and use (1 +0.09)^0 for T =0 and so on for the following years in order to get the present value for each year. However, as I continued into this problem I got more and more lost. Please help me as I don't understand this assignment.
