Migrate Custom web application

My custom-built web application is currently running on a self-managed VPS. I have purchased a new domain and shared hosting plan and now need the entire site—including database, media, cron jobs, SSL and email settings—moved across and brought online exactly as it works today... (Budget: ₹1500 - ₹12500 INR, Jobs: Database Management, Linux, MongoDB, PHP, SSL, System Admin, Web Development, Web Hosting)
