See these sealing machine not generating too much sales, you can expect 2-3 sales initially, at the same point there is very less competition.
Regarding monthly sales of range you provided is too long, see product sales value differ category to category. So if there is a product in home and kitchen which rank 200 but you are unable to see it in our PRT due to any reason then set a range like 195-205 and see sales value of all the product, this will helps to get an idea about monthly product sales.
