Ive spent years and actually when i do accept consulting offers for smaller things like domaining though I have some of best niche based domain portfolios in the market, it is because i have developed a proprietary method to find names that no machine or app can pick up. I'd be happy to both offer you some of my expired domains if your interested in any niche or focus for prices that are 5x lower than the ridic overcharge every other website or service does as a way to establish proof of value but more importantly i do have about 5-7 people looking and bidding to pay me for my methods, some not competing with each other most of them arent mostly because i have very specific formulas for specific types of domains and types of industries.
If interested PM me, one of my newer ventures has made good ROI already no overhead with very little work because of my ability to procure and centralize all we need to monetiez these domains without any additional labor, so I would be willing to teach it and sell some at the right price and if your looking to do it seriously i would be open to work with new people as I simply have to much on my plate lo
