I got a job offer a couple of months after I had submitted under SMC, from an accredited employer. London branch as well. They began processing my application within a week of me faxing in my offer. What I have learned in this process though is that there are no definites or guarantees at all, especially around time lines! My employer-to-be is flexible about start date, as they have experienced waiting for immigration before, so seem quite understanding of the lack of certain timelines. I would submit your application if it complete. theres no reason not to get the clock rolling whatever you decide. good luck.
