Looking for an expert PHP developer with good experience implementing CAPTCHAS. I have a change for a one page database driven form on one of our clients websites.. Client is getting a lot of SPAM submissions. So the client wants to add some sort of server side captcha checking.

It should be above the submit button. A few key points about the CAPTCHA:

1) Any labels should allow French or English (The page has an English and French equivalent). The captcha itself which is usally a series of letters or a mathematical question does not matter since its in a universal language. But the label (ie. Please enter the following characters) will need to allow French or English (recaptcha can do this as per [url removed, login to view]).

2) I would like a captcha that is not difficult. Often I am faced with an overtly difficult CAPTCHA. I am open to any Captcha that will integrate well. Recaptcha is one option([url removed, login to view]) although I am not sure if its better to use our own since we'll be reliant on Recaptchas service (I have generated the keys for that if thats whats decided)

If you feel using another CAPTCHA is better then I am open.

3) Its critical that in the event that the user clicks on submit and enters the wrong CAPTCHA information, you make sure that all data in the fields do not disappear and reset. So whatever CAPTCHA you use, it must preserve the data in the fields (this INCLUDES uploaded documents). This form contains various upload fields that allow the user to upload a file before submitting the form so you just need to make sure nothing breaks.

4) In addition if its not too much work or problem, you can incorporate the simple honeypot method as per “[url removed, login to view]”

Kindly confirm the cost and your thoughts/suggestions. AGain, remember you are modifying an existing form so its critical you test the form to make sure nothing breaks when implementing the Captcha.

I will only consider bidders with at least 20 perfect 5* feedback. Its critical the bidder knows how to test well. Link to form will be provided in PMB.
