I have an idea of starting my own business and I need your feedback guys. Literally appreciate any kind of feedback.

So Im an android dev who has 3 years experience under his belt. I am working fulltime and I think its time to scale. I want to open my own agency where I would take on big clients and build apps for them. I personally am able to manage/see through the whole project, handle all communication and also work on the android side if necessary. I would start from smaller projects worth of 30-40k for startups, basically create MVP for them and charge for support after that.

Problem is that as far as I understand if you want to "open your own kitchen" you need to be well connected. I dont know any big clients who would trust and purchase my services, because after all who I am? Im nobody just a dev at this moment. So I need a strategy to build some relationships with businesses.

So Im thinking long game. What if I would first open a recruitment/hiring agency? I would focus in specifically mobile dev recruitment. I have the soft skills and I already participated in dozens of recruitment processes. I also have the tech skills, I would be a competent recruiter. Maybe I could do that for a year, just communicate between devs and clients and place devs. My thinking is that in around one year I would be able to build a massive network of clients and devs.

And then, I could try opening my own dev agency. Using my gathered contacts hopefully I could land some decent projects for start and build my team or outsource from that point on.

Ofcourse Im not sure if I could pull this off alone, I would need a detailed strategy and some mentoring. But what do you think is this a viable plan?
