How can I incorporate a variable sales training period in a monthly sales forecast?

[JC Marshal]

What is the best formula or best way to make an adjustable / variable monthly sales forecast that takes into account a time delay for training before sales are recognized?

I am building a Monthly Sales Forecast that is based on a variable number of new sales people being hired and a variable number of months for training to be completed prior to the first full month of sales.

Example: Training period = 2 months; New Hires per month = 2, Sales per fully trained sales agent = $1000

The table should be able to adjust sales amounts based on any adjustment to the training period. Also, is it possible to use a partial training period such as 2.5 months and have a half month of sales reported in the correct cell?
