Where can I find someone to make a script to decode this captcha?

I'm looking for someone to create a script that will work on Linux to decode a captcha:


It's made difficult due to the close together letters.

I hired one person from Freelancer to create a script, but they disappeared. There doesn't seem to be anyone on there who has the skills to do this.

Does anyone know where I could post to find someone who might be able to do this?

A human captacha solving service is not an option due to volume.

    Youd save waaay more money by just integrating with a captcha service like deathbycaptcha.

    A custom 'script' would involve building a visual recognition system, and would likely extend far beyond the application of any freely available libraries. Even then, youd have to train it on the types of captchas youre dealing with.

    Even enterprise level software integrates with 3rd party services. The implications of a custom build for something like that are disheartening, and you're freelancer likely realized that.

      I've made a number of scripts myself to decode captchas. Relatively simple in many cases. It's relatively cheap and easy and can be done with PHP/Python + the open source OCR, Tessercat.

      But I don't have the time to do it, nor is this something I am specialised.

      I used to know a guy who specialised in them, but have lost contact.

    You would need a couple of things:
    • Split the image up based on average pixel width for each character.
    • OCR API for converting each image character into plain text
    We have the technology.

    I really wish the internet didn't come to this ... but it is, what it is, eh?

      It's not for malicious purposes, i.e. posting spam. Though I guess the site owner would prefer I not scrape their database for personal use (not for republishing).

I would prefer not to minimize it completely however there are huge businesses based on scratching, and organizations in enterprises based on scratching, and so on. Trust that doesn't sound belittling, simply been doing a great deal of web scratching research recently and understood it's not quite recently blackhatters.
      Which spinner software did you use to generate that?

    This does not look like a very complicated captcha. I would assume that the curve/shape of the letters varies as well as the colour of the letters. Maybe even the font? More samples would be needed to assess these things.

    Taking a look at the page that produces these captchas could help to determine what software/technology is being used to make them. That would hep a lot to come up with a solution!

    The most successful captchas use background noise to confuse OCR scanners. I don't think bunching up the letters and curving them is enough to beat an automated solver.
