Too many implant quotes

I am comparing All-on-4 Dental Implants for my dad and my head is full now. One clinic sent a price in 10 minutes with only a smile photo, another asked for panoramic x-ray and CT scan first, so I trust that more but it is slower. The confusing part is hotel and follow-up. Some packages say 5 nights, some say 7, and one said temporary teeth same week but the final teeth months later. I understand there are stages, but I wish the quotes were written like a normal checklist. Did anyone make a spreadsheet or is that overkill?
