After explaining which requirements of yours are not met by GNAT, I
suggest you contact the Ada compiler vendors with an explanation of
your requirements.

I think there are three kinds of Ada users: Big Business, Small
Business, and Enthusiast.
The Big Business user writes safety- or mission-critical
software. Think of nuclear power stations, high speed trains,
satellites and air traffic control. The cost of the compiler and
sup****t is only a small fraction of the cost of their research and
development. They can pay hundreds of thousands of euros for a good
compiler with sup****t. Sup****t is more im****tant to them than
anything else and they accept the price of it. Usually, they purchase
compilers after some sort of competition where they evaluate all
compiler vendors carefully ("appel d'offres").
The Small Business user writes commercial software. The cost of the
compiler and sup****t is a large fraction of their total costs. To
them, cost is more im****tant than anything else, so they are not
willing to pay a lot for licenses or sup****t. Usually, they contact
compiler vendors directly.
The Enthusiast does not want or need sup****t because they can modify
the compiler and run-time library themselves :) The other Enthusiast
does not want to modify the compiler, but they accept that bugs in the
compiler are not im****tant because what they do is not im****tant.
Obviously, these three users have different attitudes and different
relation****ps with their compiler vendor.
Obviously, compiler vendors prefer Big Business customers who pay a
lot of money and sign multi-year sup****t contracts. However, RR
Software and Aonix seem to be also interested in the Small Business
customers.

Yes, Ada is used by Small Businesses and Enthusiasts as well as Big
Businesses.

If I understand you well, you would like to become a consultant
writing software in Ada for paying customers. Fair enough. However,
be realistic: if anyone pays you, time to delivery will of course be a
major factor.
I think you should become a seasoned Enthusiast (i.e. demonstrate that
you can write and maintain software) before people will give you their
money. Then decide who you want as your customers: Big Business or
Small Business? (Enthusiasts will not pay for software development;
they'll do it themselves :)) Hint: Small Businesses buying
off-the-shelf or bespoke software usually don't care what language you
program in, so don't tell them.
