There's noting in what you wrot ethat supports the asertion you are trying to make "t is probably a 1min fix hence the low price :) ". In fact, upon close read of it everything seems to disprove it.
Like - if you are the one who wrote that code and you , yourself, cannot find anything wrong with it - this immediately dismisses the '1 minute' claim.
The other way around, if it would have indeed been '1 minute' thing you'd definitely would have done it yourself, I am sure you wouldn't mind pocketing the money, from 'the alleged client' for yourself, rather than having to let someon else, even if whatever small amount it would have been, all resonable logic points to that.
So it's not that I don't believe you, there is noting you have ptrovided to support your assessment, and the assertion, with regards to the job.
Now on teh job. What is not sending and what it is? Explain in great detail. You see the collected data 'is sent' by the client side to a server, but this have nothing to do with php. If the server is not relaying the received data somewhere else, then you didn't say that, you said the form is not sending teh collected data. It's really ambiguous and not really helping in assessing the job, based on the little info you did forward.
Please fill-in the gaps in thebrief, and be very specific, if you indeed are trying to get 'low yet fair' bids, and not trying to abuse everybody.
