There are couple of ways i suggest it based on 15+ years I have in building offshore teams in Asia
1) India is becoming for start-up Hub now. If you want to start small, you can start searching for these companies by technology expertise you can looking for like Data Science, ML etc. You will start seeing search results with new and upcoming agencies. These are companies who are hungry for success and will literally do major development work for small prize..
2) Then there is big fish in tank but still low price . You can partner with companies like TCS , Info and Wipro and try doing a T&M 1 year contract and see if they can offer you right expertise before investing big

Like i said above , India is a IT hub , if you contact any of these companies , they will contact you immediately with proposal but there is no shortage of talent there.

Happy to discuss this on call if you need . I have been in offshore business for multiple years , i can share my experiences with you
