Check Founder Institute,fi.co
might be of your interest. I am currently going through the program here in San Diego, and It has been very helpful. Lots of work but it can only benefit, plus you might be able to find your co-founder.
Challenge #1 for very early startups with no money, is to build their 1st version of the product, good engineers are either happily working for companies, or they are building their own products, so alternatives are, find someone in the same space and empower/complement each other or you will have to get creative and raise funding from friends and family.
Anyways, good luck, and be persistent!
