build an nft generator

Job ID: 32443008

Budget: $750 – $1,500 USD

looking to create a tool for nft generator
it needs to be exactly like that in functionallity - https://nft-generator.art/app
including all the features.
here is an example video - https://www.youtube.com/watch?v=8WoytaO09So&t=63s
here is another example = https://www.youtube.com/watch?v=b3zrJUCd-10

it needs to be in my native language and english which ill provide all the info about each title or youll show me how to change strings by myself.

in order to generate the user needs to pay.
the payment will be in metamask or paypal
the tools needs to be able to create the variations based on the layers he adds organized nicely.
to each file there needs to be a json file of its metadata.

after generating it will ask the user if he wants to mint it.
this will ask him for another payment and will mint all its collection.

the script to generate the variations files is available in many places [as you can see in the video]
the main issue is to create a nice frontend, connect my metamask or paypal, create json file for each nft and the minting process suggested after

can be done in any language per your request.
if possible to do it all on wordpress it great.
already own a domain and hosting
