Your total time isn't bad but let me give you an idea how tough it can be to get those jet charter or corporate jobs. I am a furloughed airline pilot with 7200hrs, 2500 jet(B737), 2 type ratings. I have talked to a couple charter operations here in MSP and they wont touch me. Why? Because they want pilots with experience in those airplanes(kingair,citation, etc). It costs too much to train someone from scratch. What I recommend is keep trying to build that multi time but take some time to go over to that charter outfit and mingle. Introduce yourself but dont push too hard yet. You will need to work it slowly. Then when a position opens up, chances are, they will remember you and call you. Its all about networking and who you know. I hope this helps. If you need more information on how to interview, resumes, etc, come to my website, www.webjetcareers.com
