As someone not familiar with investment sourcing or SME financing. Could you break down the maths/accounting? How do you go from sinking 40k in a business to losing 6.5k if you turn the lights off at the end?
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.
Because if that exists, I want to buy them all.
You would be wise to do the software development I mentioned, do more sales and support than was covered under my initial $3000 labour fee. But that you can pay for with the revenues, it would not be the initial investment to see if it is viable as a business.
