poker game (web+mobile app)

We want to make a web page and mobile application like https://1wzmnt.top/bets/home. However, there is no need to have a betting system and different games like there. Just Poker is enough. There is no need for bank or virtual pos integration as a payment system. After the bank transfer is checked, the work will be carried out by obtaining manual approval. We want some customization in the admin panel. can you be helpful in this regard?
