Invisalign is just another way of performing orthodontics. It is preferred by many adults since the aligners are removable and much less noticeable. Since your arches require expansion in order to accommodate the crowding, invisalign is actually perfect for your case. What you need to select is actually not the method of performing orthodontics in your case, but the proper dentist who understands the relationship between the orthodontic movement, the extraction of tooth and implant placement, and the final restoration. I recommended you first see a prosthodontist to plan is the final case, and let him/her refer you to an orthodontist of his/her choice, so that the communication between the doctors is excellent. The final results greatly depend on that communication. Best of luck.
