How do I go about a patent tech transfer enquiry from India?

By design, I understand you to be referring to an ornamental design. I would recommend filing the design in the U.S. Patent and Trademark Office, being careful to include good drawings. Please also be careful to check if the Indian patent application was published before the grant. This would start the one year time period running. If the Indian application was done to standard, and cost is an issue, you could try to file it yourself and that is likely to be better than not filing. However, it is always better to get professional help to make a filing.

The grant of an Indian patent is unfortunately not going to impress any US venture capitalists or companies. Venture capitalists like to see at least one US patent plus profits from sales. Angel financing is how a lot of startups get their initial funding. Multinationals are generally not interested in hearing about inventions unless you have a champion inside a company or you have an existing US patent that they infringe. The grant of a foreign patent terminates your ability to file in the US unless you are within one year of the Indian filing date. See 35 USC 102. If you are past the one year, you could file in the US on an improvement. Then later seek contingency fee enforcement if infringement takes place.
