You also need to understand the impact of no defined scope. Typical business plans or MVP requirements will absolutely define a scope. This scope of work should match your best guess for a minimum viable product - based on your market research. This allows you to remain on budget and measure your success.
With a solid business plan, a set of strategic business requirements, a well defined scope, and 2x salary - you will have no problem finding talented developers.
I will advice you to try to place a lot more emphasis on your earlier success bootstrapping and selling a SaaS company as this can motivate people to want to work for you. Because take it from me you have done and accomplished what a lot of people can not and that is very impressive.
If you are interested I would like to work for you, but I don't know how well that will pan out as I don't know the area of specialty your startup is focusing on and if i am even 'Not Skilled' enough to work with you in those specialties, but at least I will like to get in touch with you if only in some sort of mentorship/advisory role, because building a successful Saas business has sort of always been my dream.
my email is smithmayowa20 at gmail.com I am an African developer in between.
You'd be crazy to do it any other way.
