So I managed to create ICO on ropsten testnet. But I have few difficulties

1) I want to create a webpage where users can buy my ICO. But how to do this without using MetaMask plugin? I want such that user can send me Paypal, Visa, ETH in exchange for ICO Tokens.

2) If I want to launch my ICO on live server, do I need to create my own Node or just use Ethereum mainnet? What are the benefits of using own node vs using ethereum main net or vice versa?
