Integrate Token Presale on WordPress

I am looking for a developer to add a full token presale feature to my existing WordPress site. The presale section needs to be user-friendly and mobile-friendly so that users can connect their Solana wallets and participate in the token sale with ease.

Key Requirements:
- Support for Phantom, Sollet, and Solflare wallets
- Token purchase calculator allowing users to enter amounts in SOL or USDC and calculate the number of tokens received
- Real-time exchange rate updates for accurate token calculation
- Transaction confirmation messages for user confidence
-
- Progress bar showing the percentage of tokens sold
- Real-time display of purchase transactions

Ideal Skills and Experience:
- Experience in WordPress development and plugin integration
- Familiarity with the integration of the Solana blockchain and wallet
- Ability to create responsive and intuitive interfaces
- Experience updating data in real time and processing transactions
- Good communication skills and ability to work in a team

The work is simple, but important. Payment only in full upon completion.
