Looks like a good program, especially for a low time pilot.
I did my initial training at Simcom. If I recall, SIC training was about $8k, way cheaper than FSI. The SIC check ride is to ATP standards, and is the same as a Type ride, except for a few items. The SIC type came about when countries like Mexico started to enforce that pilots must be type rated to enter. So the FAA made the SIC type, nothing different, its just added to your certificate.
Unless your training is in a level D sim, some air work in the aircraft is required to complete your training. This may have changed, but worth looking into.
The bottom line is that anyone who has training completed saves the company money and is therefore more attractive.
Airlines may not allow you to fly on the side, some do, some don't. Corporate operations are wary of 121 guys, but, if you have current training covered, the risk to them is lower.
FYI, a PIC type rating in the HS125 at FSI is around $25k. Also, the insurance industry is the driving force in corporate. 2500tt is the min. for most companies even for a copilot. Unless you know people, you can see why so many pilots go to regionals or haul freight to start.
