Great question.
You should definitely not drop the idea if you think that it is worth pursuing. Just like you need the tech-founder, he needs a business founder with a dream, and the passion to make it succeed.
I suggest that following:
1. Do market validation/ POC to see if the idea has potential (get a general idea of how here: https://clarity.fm/questions/6423/how-do-you-do-market-research).
2. If it shoes potential, start looking for a tech-co-founder. There are numerous ways (try these):

www.founderdating.com
www.cofounderslab.com
http://www.founders-nation.com
www.founder2be.com
Linkedin...

3. Do a trial period + sign a founder's agreement.
Happy to help you with any of the above once/if you need.
Good luck!
