The World Bank has a great resource here which lists out pricing for emissions trading systems (ETS) and carbon tax by country.[0] (Map & Data > Price > Type of Instrument). Highest carbon taxes are $100+ / ton (Sweden, Switzerland, Lichenstein), high initial value for trade is about $50 (EU, Switzerland).
We are a bit behind in the US in credits or taxes, we are now treating the social cost at $51, but not using that for tax or trade policy.[1]
There's one more number that is useful to get a numerical sense of the costs: $258 / ton, an estimate of the actual cost to society. [2]
I can see the appeal but would recommend against pursuing large name brand companies at this point. If your solution does what you say, that’s already incredibly novel and interesting to the right buyers; people are seeking these solutions out. The real question will be: what’s the cost? So scaling and cost reduction is where I’d focus. It’s likely non-trivial to go from 1 ton, to 1000, to 1 M.
If you’re looking for a novel way to generate excitement, how about the X-Prize?[0] You’re doing a demo of “1 tonne of CO2 per year“, that’s enough to enter, and entering is enough to tell investors. Doing well could provide dilution free capital, technical validation, in addition to free publicity.
