Dcc That's a overkill.
First of all, I would go with only DigitalOcean (it's easy to use if you know how to setup your own server - better and cheaper than AWS or any other cloud services)
If I was to host Foodomaa with the stats that TitozzTitozz mentioned, I would go with the $24/m plan (Premium Intel Nvme SSD 4gb ram, 2vCPU)
And after a month scale to $48/m plan (8gb ram and 4vCPU.

And if I have some more money to spend, I would go with the CPU Optimized Droplet ($80/m) - 8gb ram and dedicated 4vCPU - this is really good one.
You should be able handle 500 orders/day*
*Depends on how many restaurant owners and delivery guys you have.

We have done some load and stress test on Foodomaa and found that Foodomaa is more CPU intensive than RAM. So if you take Memory to CPU in the ratio of 2:1, it should be okay. (Example: 4gb ram 2vCPU, 8gb ram 4vCPU)
(We have already optimized many RAM intensive stuff already on Foodomaa, so it's chill on that part)
Also, for everyone reading this and want to have a dedicated hosting, if you setup your own server, go with VestaCP.
It's super easy to setup and use (if you are comfortable with SSH and stuff)
The awesome thing about it is, you get a reverse proxy with Nginx, i.e all the static resources like images, css and js are served over nginx which is faster than Apache.
