Coles Company, Inc. makes and sells custom designed window shades to large stores such as Home Depot. The window shades are designed to customer specifications and produced after an order is received. Shades are shipped immediately upon completion of each job. Budgeted sales of window shades for the next three months are $($in units$)$:

August $15,000$ September $16,000$ October $15,500$

Each shade requires four yards of fabric that Coles purchases from an outside supplier. Coles has $18,000$ yards of fabric on hand at the end of July. Coles wants to carry an ending inventory of fabric equal to $30\%$ of the estimated sales for the following month.

Assuming the forecasted sales are accurate, how many window shades will Coles Company produce in August?
