Invoicemachine Clone

If you cant do this job exactly as requested , DONT BID. Please, dont waste your and my time. I am looking for a complete feature set copied or clon of Invoicemachine website, this is an Invoicing website, also the website must be created not just the features. The Website design can be similar but not the same must have different colors will be discussed with the person who gets the job. Feel free to setup a free account with them to fully understand the functionality that I am asking to be reproduced, also take the free video tour so that you will know what features are needed they all must be the same they offer. The url for the website that is to be used as the example for this this project to be based off of is: [login to view URL] You should be very familiar with php, ajax, mysql and making the script downloadable and installable on different servers. Security is also of utmost importance, you must provide instructions for the Script Installation and of course you will do the first installation. I need someone trustworthy, so - someone with good reference is needed. I do not have a lot of money, so, someone decent, that doesn't charge an arm and a leg. Maybe in the $1000 region. I need references of your html, css2 and css3, ajax, and php and mysql skills on previous projects, will be great to know you have done a job like this before please provide your samples. If you have any questions please feel free to ask me, I will reply asap to all questions, thank you.
