Research SS7 network access and configuration

Hi, search for someone who can access the S77 network. Person know how to request HLR, and other action on SS7 network... access from API, why not. I got scammed already (no money advance). Open work for anyone who knows how to do ! If you know how to do it, perfect. 100€ per request, 4 request per day (or more). 12000€ per month. Payment after each request. Come speak privately. thank
