hey jayC
Sorry to hear your suffering too, in this case tho, i really do know how you feel

for what its worth tho (and im by no means a profesional) i dont think an infection in a suture site would spread that easily to the plates and screws, as one would be a local infection in the skin tissue and one an infection deeper inside. (as i said tho this is just my guess.)
I know in my surgeons case that taking the plate out was an absolute last case sceniro, after the antibiotics failed to do anything. But you must give the antibiotics time to work (at least 3 days) and i dont think your notice a difference hour by hour.
By the way no ones mentioned taking both plates out of me, only the infected one, so you may not need them both out. Cant help with the payment thing as im in the UK-sorry.
If you have any questions please ask me

im crossing my fingers for you.
