Skillsbridge Program  

To answer the OP's question: Metro Aviation offers a Skillbridge program. I talked to them last year at the RTAG convention about this exact thing so my knowledge is first hand from a Metro recruiter. If selected and approved you would attend the company basic indoctrination program to include aircraft training, qualification and Part 135 checkride. Then, you would probably be working as a traveling line pilot (typically called a float pilot or pool pilot depending on the company). You would not receive a paycheck from Metro (Metro can't legally pay you while you are still on active duty and in the Skillbridge program) but all your expenses (travel, hotel, rental car, per diem) would be paid while you build experience for when you return to Metro once you are on transition leave or officially retired. You CAN legally draw a second paycheck while on transition leave. 

If you think you may be getting a 100% VA disability rating, I think the first step would be to share all of your claimed issues with a Medical Examiner so that you don't get grounded after receiving a Medical Certificate and are then found to have a grounding condition once you receive your VA Disability letter. You should know what is a grounding condition and what isn't but if you don't, do the research and figure it out before you dedicate too much to going down a road that is a dead end.

If you've got issues in your medical records that are service connected, file a claim for them. What is a nagging neck, back or knee issue now may very well be a grounding issue 15 years from now and you deserve to be compensated for it. File the claims and let the doctors figure out what is or isn't service connected and what the percentage should be. Don't let anyone shame you from filing your VA Disability claim but once you have it, don't broadcast it since it obviously upsets some people. I recommend you bank all of your disability checks since there is a good chance you'll need that money for those medical issues later in life.   

Take everything you read here with a grain of salt and don't take part in the negativity. You will probably have to make some sacrifices in the form of pay, schedule and/or location to get what you want but all the heli jobs in all sectors are good jobs if you have a good attitude and genuinely have an affinity for the type of flying you will be doing. Go for what checks as many of or all the boxes as you can, apply yourself, don't get on the adversarial side of the fence and you will probably have an enjoyable second career. Be the kind of person you want to work with and you'll be fine. Good luck and thank you for your service.
