I think you have to first familiarize yourself with the pool rewards mechanisms and why people would delegate to your small pool.
If your pool indeed is small (<1m ada) delegating to your pool would mean accepting about 65% of the rewards when staking at a big pool. And that is assuming you can be trusted to be online and properly managed optimally, which also you yet have to prove. So people must either be ignorant or have another reason to delegate to your pool.
That “another reason” is your job to provide! So ask yourself what added value you can provide to delegators/community. Then start addressing that added value and mostly deliver it and keep up at it!
I would say, one thing is pretty sure. People won’t just delegate to you if you don’t add more value than another pool.
Summary: it is just like starting a business. You have to work hard at it and provide value.
