I want to have my belly flab removed and a reduction and that belly band put on my stomach.?

I live in Arkansas. I have had one shoulder Broke work injury, the other one has been dislocated at least 3 times in 29 years from work injuries. I wear a 40 DD bra. Have degenerative spinal disc disease and my hanging on my shoulder hurt my shoulders all the time. Would a reduction help this? And I have been big all my life. When I met my husband in 1981 I wore a size 10 clothes now I wear a womens 26 or a 2X pants and a 3X shirt. I roughly weigh 275lbs. I have tried all sorts of diets NOthing works. Do to current health conditions Exercise hurts my joints and my hips and back to much. I know it is from all the weight I have on my bones. I have tried ATKINS diet, Slim Fast Diet, Diet Pill, Gfruit Diet, and so many others. And once I go off the diet I just gain the 20 pounds I lost then 10 or 20 more. My hole family if rather large. I do not eat that much in a days time I just can't loose weight. I want to have a tummy tuckI have about 4 or 5 inches that hang down off my belly and it always gets sore in the summer from sweat and It will crack and bleed from being sweaty under there. I usually have to put a bandage under it just to absob the moisture. But not sure what these surgeries cost or even how to go about seeing how to do them.
