Don't take this the wrong way...
Insurance companies often require hundreds of hours of multi and even several hours in type to be covered in a Seneca or a Baron. What makes you thing that with 390 and 20 that you should be in a Hawker? If I were you, I would try to get some experience in something more your level, such as a Duchess or a Seminole.
I am not trying to bring your down, just trying to put things in perspective. You really have no business in a commuter aircraft.
