I'm sure pfk can make a mould for themselves if they take this job seriously. And that can only happen if they're shown hard evidence of significant demand of maybe 10pcs of 10ft dishes or more. Then they'd do their costing, add a margin and give us a price.
Perhaps we can also give general estimations by way of posting here, how many of us would buy a 10ft pf dish and what price you're willing to pay.
If demand is good, We'd then approach them and say look, we need these pcs at this price with the these instructions prepare a mould and produce them.
