I believe your Sales figures are too low and your PE too high at least for the current bearish market.
These are my estimates : Sales $ 120 M and Gross Profit around 20% = $ 24 M PE = 15 for current growth stocks OS = 8,200 M shrs ===> PPS = 15*( 24 / 8200 ) = 0.044
If sales are like you estimate Sales = $23 M and Gross Profit around 20% = $4.6 M PE = 15 for growth stock OS = 8,200 M shrs ===> PPS = 15 * ( 4.6 / 8200 ) = 0.0084
