You buy the hardware (48 servers), rent part of a colocation rack with a 10 Gbps or 100 Gbps internet transit link, get a payment processor, make a webpage and GitHub demo with the API. Break down: $3000 labour, $20.5K hardware, $800 monthly rental fees, $376 car fees. When you shut down within a year, the $20.5K popular off the shelf hardware can easily be sold for $17K, a fact you can check from 25 years of data.

I would invest more than the initial $30K on optimization after the servers have found paying customers and thus have proven commercial viability. I would invest in software development, finetuning, retraining and above all reverse engineering GPU and neural engine instruction sets and adapting these open source models to the more than 2 quadrillion operations per second that these 48 servers can do.
