Front End and Backend Developer All from Scratch

I am looking for a php develeper who is very good in coding , and laravel and codeighter , We are a truck agency, at the moment our website is [login to view URL] , auto trader are the once that build and host this site for us, so they have a portal they provide us and we do all the listing on their , when we do the listing on the portal, it automatically come up on our website, This is all great but as you can see our website isn’t not nice or great , so we decided that we want our own portal and new website , where we will put our truck listen got our own portal and it goes live to our website. But one thing we want is , the portal of auto trader , its perfect portal , its easy to use , responsive , and we are use to using it. I have got all the screenshots which will be attached here of how the portal is and the section of each, So we looking for someone very very good to developer extractly the same portal , design and functionality, if not identical but very very close. This is for the back end side , so the front end , the good news is we have design everything on psd for the developer so it make their life easy. We have work with many developers and paid and they never deliver what we want . So we are willing to spend but we are not just willing to pay straight until we see that they are doing the right thing, we don’t want to waste money and time again. I will be available 24/7 to help the developer in guiding them on how we want it . So first what we want is , the developer and I have a live chat where they can have access to my pc screen and can also speak on the phone , so I will explain to them each step , I will open auto trader, for them explain everything and how we want it . So then they have to design or do a mockup on how exactly the backend portal will look like , this will make us understand that they have understand our needs and also have a good solution on doing all the work without coming to us and say this is an issue I can’t fix it etc. So we don’t have a very massive budget , but we will pay according to if the developer is very good and the mockups they did are exactly what we want. For time scale, we want this all done with the testing within 6 week MAX. Please don’t bid if you really don’t get or understand much . I only need advance developers and also this project urgent so I don’t want people that don’t reply early on time or take too long to solve issues or do work. Thanks you
