Some uplink providers offer BGP+IPv6+IPv4 in a bundle. (he.net)

Since you can operate 32-40 nodes with 4-5 IPs, this would be an option
to start with. With fast CPUs (clock speed), you can do around 10G of traffic.
For a /24 then put yourself on the waiting list at RIPE.

That's good. You'll quickly notice that you can send well over 90%
of the abuse directly to /dev/null.

I would ask about IP leasing for Tor exits here:

I would rather try the RIPE waiting list. AFAIK 4-5K for a 24/
You will then get IPv6 for free.
It also depends on the taxes that you may not have to pay as an NGO.

Write them a sad story, e.g.:
You are making free wireless networks for refugee homes. This is more popular
than Tor exits and could shorten the waiting time.

Years ago I looked for a /24
1350,- / year

[Off Topic:]
With IPv6 only everything would be easier:

NTH mentioned it at the last meetup. IPv6 only nodes must be possible in the 
future. The reports in recent days have made it clear that the Tor network 
needs to grow.
- Some UNI's or companies can only provide IPv6 for Tor nodes.
- Individuals can only pay for IPv6.

In the next 1-2 years, the Tor community should aim to have 70-80% of all 
nodes dual-stack. Less than 50% of guards and middle nodes have IPv6:
https://nusenu.github.io/OrNetStats/#ipv6-relay-stats
People using Tor in IPv6 only cellular networks can use *less* than half of 
the guards.
Since the IPv6 setup is different for each provider, it might be helpful if we 
collect the configs on Gitlab or Github.
