I've one of my automated email responding script what can reply automatically with specific time delay and multiple reply message. But, it's working just with one email account and I want to now use as many email account as I want at the same time. Each email will be reply from the same email account and want to improve just some more thing like if the Script has some issue on the coding. I am looking a Developer who can working with me long term basis. Because, I will improve this Script on every month and I've once more Script what I need to improve. And, the Developer cost must be affordable for me what it should be. I will show you and send you my Script if you're able to do it. I need to finish as soon as possible. Please, it's only for experience and highly skilled PHP Developers. Not for beginners PHP Developers.
