All 3 are Coalition members so they are all at the top end of the scale.
Just looking at your pictures. You may be able to regrow a substantial amount of hair by taking Finasteride and using Rogaine Foam. Any of the 3 doctors can write you a Finasteride prescription but remember that you will need to wait 9-12 months to start seeing the results. At the very least they should rapidly slow down the rate of hair loss.
If you have a transplant at the front you obviously don't want the hair in the middle and back to disappear rapidly in 5-10 years. You will look silly or have to get another transplant.
If you kept your hairline where it is and added density I think $10-12,000 is the ballpark figure (2,000-2,500 grafts). But my advice is to get on the medications for at least 9 months and during that time visit the doctors and keep researching.
