In my experience, scaling a consulting business is more to do with sales and building long-term relationships. Sales is a skill that can be acquired, and you don't have to be very good at it to get started. Learn the basics of business development and sales; try experimenting with different approaches. See what fits you best. IMHO, I think the problem is "getting projects from 0 to POC/MVP state." These are projects…
I believe there is a lot of value in helping clients determine what an MVP should be (i.e. understanding of the business problem to be solved) and then help them validate solutions by building (or helping them build) an MVP. It appears the OP has the skillset to do both, and off-shore dev shops can't do that.
Plus, you need a good understanding of local practices, culture and market to be any good at this.
