My question is, do you think it a commercially viable concept and if so, what do you think a fair retail price would be on it?
Hello Craig
Firstly let me congratulate you on your creative streak. Most performers rely on others to do their thinking, so well done.
You have of course asked the $64,000 question.
I'll answer the second part of your question first. It is worth whatever people are willing to pay for it. But, look at the price of most magic effects - just a few pounds.
To answer the first part, that depends on the price!
A sort of catch 22.
You need to ask yourself the following questions:
Where can it be used?
Who will use it?
What do simmilar type effects cost?
How many am I likeley to sell?
What will it cost to make?
What will it cost to advertise?
What profit do I require per item?
If it costs £10.00 to manufacture (in materials never mind your time cost) and sells for £30.00 you have a simple unit profit of £20.00 (I'm not suggesting that this should be the price, it is just an example). However if you advertise the effect and it costs £200.00 per month to advertise you must sell 10 per month just to cover your advertising.
To make matters even more complicated you have to allow for the cost of p&p and also for income tax.
This is why most 'inventors' will sell the rights to an effect to a magic dealer.
You need to remember that a simple packet card trick that costs a few pounds can sell to a wide range of magicians. Something like 'The Scryer's Seance Box' will find itself in a much more limited market. For example it apears to need a 'captive' audience who will sit quietly and listen to the proceedings. So the market is readings and seance performers. They will demand top quality props but will be willing to pay extra for them. But there are a lot less of them.
Well as you can see it is a very wide ranging question that really needs a more complicated answer than I can give you here.
At Black Artefacts we only sell effects that I have developed myself and manufacture myself, so it can be done and it can make a living for you. However you need a whole range of products over which you can spread your advertising and other costs.
Whatever you do with the effect Craig, I wish you the best of luck.
