Customized BEP-20 Wallet with custom swap page

We would like to create a custom wallet for our token as well as a custom swap page.

We would like to copy something similar to this wallet and have it themed to our project:
https://play.google.com/store/apps/details?id=net.safemoon.androidwallet

The user needs to be able to setup their wallet, agree to terms, etc.
Tokens should be limited to only our own, BNB, and BUSD.

Some sections of the app include:

BEP-20 compatible wallet:
- Send token
- Receive token
- Buy (Integrate payment with moonpay)

Swap:
- Allow custom slippage
- Allow speed adjustment
- Allow max tx time
- "From" token only BUSD or WBNB
- "To" token only PETS

Settings:
- Option to Allow fingerprint
- Option to Enable two step authentication
- Ability to reveal passphrase
- Ability to reveal private key

In addition to the wallet, we also need a customized swap page themed to our project similar to these:
https://swap.thehappycoin.co/
https://swap.safemoon.net/

Same swap features as wallet
Only interested in the swap
Tokens should be limited to only our own, BNB, and BUSD
