Good points.
Airnet DOES have an SIC program, and tends to cater to those with around 800-ish total and low multi. They are quite an exception in that you are getting PAID in the right seat until you meet 135 PIC mins. It's not a bad gig, if you can live on the pay for a few months. I believe they make you sign a 1 year contract after your PIC checkride.
Other companies that sell time (Eagle Jet) are pretty much PFT, although in some instances I suspect it would be considered PFJ. If you look at their website, they have photos of Ameriflight aircraft (one company you can buy SIC time in) but with the titles whited out:
