you need to take proper pictures to get help, thats front on and profile of your face, not party photos or instagram style photos
that said from what i can tell, you are quite good looking at the moment and should be cautious about getting surgery. Im surprised they suggested implants since your cheekbones are not retruded at all and its this area in particular i would be really careful about - ask to see examples of patients who have had this done and see if you like the look. Most of the silicone cheekbone implant results Ive seen have not look natural after.
As for surgeons, I cant make any recommendations for US ones. Gunson should be able to recommend surgeons himself if you explain you simply cannot afford their services.
If you're willing to travel, There is Dr Raffaini in Italy who has some of the most pleasing results aesthetically I have seen. I'm not sure if your insurance would cover that you would have to check with them, but he is significantly cheaper than A&G (Raffaini is roughly up to 20k euro depending on the procedures, as opposed to A&G who average about 50k US)
