OpenSea - Bulk Offer Bot

I am looking for a bot that can automatically make WETH offers on Collections on OpenSea.

Bot Inputs
- Collection URL
- Metamask
- Bid Amount
- Bid expiration time

The Bot should take collection Url as input and starts making offers on arts of collection.

OpenSea Apis Bot
Build on Opensea Official Apis.
The Bot should be fast and robust - It does not need to sign transactions.
The Bot should make offers with custom expiration time from 1 minute to 6months.
The Bot should never break because its light weighted and uses open sea Offical Apis.

see https://youtu.be/hGNHiymdzyA?t=292 for what I want.
