Cost of tummy tuck and breast lift after weight loss? What are the best minimal scarring options? (photos)

Hello dear!
Thanks for the pictures and provided information as well.
Based on your photos, you are a great candidate for liposuction, breast augmentation with lift and a full tummy tuck, to give you a nice tight tummy and get rid of the extra skin.
Along with the tummy tuck, liposuction allows your plastic surgeon to transform your entire shape. You improve your waist, back and flanks.
Breast augmentation with the anchor lift. Implants will add to your skin will be a lot, so, you'll totally need a lift and your breast are already sagging. You may want to consider breast augmentation sub muscular. 
Know that the size, profile, and shape of the implant is based on your desired breast size/shape, your chest wall measurements, and soft tissue quality.  This decision should be based on a detailed discussion with equal input from both you and your surgeon.   
It is important that you communicate to your board-certified plastic surgeon what are expecting, to make certain that your goals are realistic. It's helpful to show pictures of results you'd like, but please keep in mind that these are other people and your body is different from everybody.
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

Congrats on your weight loss! Based on limited photos you appear to be a good candidate for an extended tummy tuck with muscle tightening, as well as breast lift. Scars are the tradeoff, and with the right scar management they fade overtime. Prices will vary from Practice to practice, depending on Surgeon's experience , facility that they use, Anesthesia etc. I suggest that you seek the most experienced Surgeon for this job. Good luck!
