Opensea-Like NFT Marketplace Development

I'm seeking a skilled indian company/developer to create a blockchain-based NFT marketplace similar to Opensea.

Chirag please prepare one doc with a timeline of  features that are present in the Opensea because the client wants to build similar to the same as opensea
 
Questions that we asked to the client:
1. Which blockchain you want to support to start with ?
2. Do you want Fiat payment gateway or crypto only or both ?
3. Do you want to integrate bitcoin ordinal nft or not ?
 
Answers:
1. *****, ETH and Solana
2. USDT and *****
3. What do you recommend me?
 
(**** names are hidden)


I would also like that if someone creates their own collection on their own page it can be displayed within the marketplace as usually happens in opensea



Key project requirements include:

- Full development of a user-friendly platform allowing for NFT buying and selling.
- Capabilities for NFT creation and listing.
- Security is paramount. The platform should be built with advanced security measures and encryption to ensure user safety.

Ideal candidates should have:
- Demonstrated experience in developing NFT marketplaces.
- Proficiency in blockchain technology.
- Strong understanding of security protocols and measures.
- Prior experience with similar projects is a plus.
