I agree with Ian. It really depends on the scope. Definitely start small with your MVP, test user interaction and iterate from there. I caution against using freelance developers just because of your inexperience. You'd need a project manager that understands development to act as your intermediary, which will cost more. My company works closely with startups to build our first iterations and help them grow from there. Feel free to reach out with any questions or visit our website gaslightworkshop.com
