again looking for someone thanks
There are tons of developer here but cannot really risks the work for an anonymous offer. If you want a quality developer that would fulfill your offer within a timeframe, better try Fiverr or Upwork, since it shows good freelance developers with reviews and the payment is based upon the on the developer's price and agreement. Another way is if it was a bug, try making a bug bounty campaign which you can do here in the forum. Jobs offers like this often have less attention as many dev users in here aren't freelancers.
