Good luck with that.


There is no one who will cater to your specific demands for what are essentially the specs for 3 unique prototypes...at the price you are quoting. It ain't happening.


You will either have to compromise on your demands and find either a project that comes close to what you want
or a current device being offered that comes close ....

or

If you insist on your spec list and prices and demands...
Then you are going to be one busy fella trying to find and convince the hundreds ...most likely thousands of investors / buyers to see the logic of what you demand...and join you....
and of course I am sure they won't have their own set of wants that will intrude on your plans.


if you didn't put the price tags on...then with unlimited funds available I am sure someone could make your device for you...
but
I think a manufacturer would either dismiss you or laugh.
demands of a manufacturer with the only option being a choice between 3 price tags that don't come close to the prototype cost ....and with no funding? no down payment ? no deposit?
You risk nothing...
you back the venture with nothing...
perhaps "20€ or 50€ with a little discount on the final product, but I will not preorder."

the maker assumes all the costs ...
all the risk upfront..
in your scenario...

Just for a running current example...
look how hard it was to gather enough people to start the neo900 project...
that took a long time...
a lot of.
and then there is the "universal constant" ..
.the fewer investors...
the fewer the units in production the more expensive to build...
the more ...the cheaper.
But everyone here knows all that fun stuff.

Personally I do enjoy seeing what others would like in a device...
and what they can afford as a price tag...
and I did enjoy seeing your wish list ...
and on the whole of it...I wouldn't mind half the stuff you also want...

but unless you build your dream device yourself ...
with the budget you have in mind...(who knows ?...you may get a lot of what you want in the prototype with your budget if you build it yourself...but frankly I doubt you will stay under budget ..)
....I must admit what your specific individual demands and requirements amount to is.. the smartphone version of Fantasy League Football.
