I suppose we could use Drake's Law: I'd estimate that perhaps only 1
in 10 Hams are interested in homebrewing, 1 in 10 have the skill, and 1
in 10 have the means to stock up a large parts library: basically an
interested audience of 1 in 1000 hams, meaning an audience of no more
than 700 hardcore homebrewers. Can that be right, only 700 of us
potentially on this newsgroup?

Although, if I provide the service of the homebrewer's parts library:
reasonable price, fast shipment, good ranges of discretes for 160-6 M
construction, then I could address up to 7000 hams who have both the
interest and skill who don't want to kit but do want to try something
new.

If I bundle the parts kits with the FAR boards, I suppose I could
address the 1-3 additional people on the bottom end of the skill scale.
Now we have an audience of up to 21000 hams, a nice healthy audience.

If only one of 100 hams in the kit audience buys a kit per year, then I
have only 210 sales per year. If the average parts kit cost me $50 and
I mark it up by $5 I only make about $1 of profit per kit after taxes
and expenses. 210 sales per year X $1 per kit is $210 per year. Not
good!

Or are there things of which I am not considering.

Yawn,
