How much to charge for the development of an electronic board, firmware, production and its support?

Question

Do it yourself

Good day.
I developed an add-on board for my machine. I showed it to the manufacturer of machine tools, they liked it, they
asked - how much?
How much I don't know myself. Since electronics is a hobby for me and I'm not a professional yet.
The board itself consists of a 7-segment 4-digit indicator, an encoder and a pair of mikruhs.
10 x 8 cm double-sided. The firmware is self-written. According to the components of 700 rubles, it turned out ready.
By my standards, the simplest.
To find out the price, I went to a local automation firm, according to my requirements, it turned out 50,000 for a prototype, 2,000 for the production of each of the 50 pieces.
Here I got a little crazy about the cost of development ...
Actually, questions, for the sake of interest:
How much is the real cost of developing such a simple board? How much would you take?
Who in Russia can order the production and / or installation of printed circuit boards, with a normal attitude towards beginners (for an additional fee)?
Thank you.

Answer 1

Not less than 10 tyr. For a test instance. You should look at the pay.
The balance is important - you take a little, they will not respect and appreciate, a lot - they can refuse.
But if there is a minimum of orders, but you want to get involved with the office ....
Yes, the offices have large overhead costs, so they charge a lot.
I consider the cost of development so.
I estimate the desired salary (real) for how much I would work on a permanent basis. Multiply by development time.
And I multiply by 2. At least for the reasons that you act as an individual entrepreneur and you bear all the risks. If you get sick, no one will pay you sick leave.
The workplace is also yours, etc.
Farther. Boards can be ordered in Russia (Rezonit, Tepro). Expensive for preparation, normal for a decimeter, quickly. Or in China - preparation, for a decimeter cheap, long.
We definitely have to solder such small batches.
Where to find board manufacturers. There are contract manufacturing. They may not be satisfied with your small volumes.
There are freelancers (solderers at home) - you need to look for them on the forums, in the Job offer section.
I don’t know the price for the soldering point, look for the info.
You give them a fee and a package with a complete set, they give you a fee in a couple of days.

Show the boards, maybe I'll tell you something else.

Answer 2

The company, it seems to me, received 50,000 something like this - (developing hours) x (developer salary) x (taxes) x (risks) x (profitability + greed of the director / superiors + staff maintenance a la secretary / accountant, etc. )
You can calculate your cost using a similar formula, and about the same cost of support.

Answer 3

Order production better in China. ON Habré there was an experience of people, shared. It's the cheapest, there's a whole market for it. We can only decide on this because of problems with customs.
