Laravel Developer - Customise one script

We are a Web Agency from Germany established 15 years ago. We hire developers to extend our team and to outsource tasks for new and running projects. Now we're looking for an experienced and reliable Laravel developer to customise and extend an existing script (it's installed and working already). You need deep experience in Laravel (besides PHP, HTML, CSS, MySQL, Javascript, jQuery) and payment integration (Stripe and Paypal) too. The script provides users a basic analysis of their domains for free (Analysis A). The task is to customise and extend the script: 1.) After purchase (Stripe + Paypal) create a professional analysis (Analysis P) with API data (we give you the API access). 2.) Save "Analysis P" as PDF file (with our branding). 3.) Send PDF file to buyer's e-mail address. 4.) Send invoice to buyer's e-mail address too. 5.) Add "Analysis B" (similar to A) comparing the data of two domains next to each other. 6.) Make some design changes (e.g. text formatting, showing error messages, promo page, etc.). 7.) Show users' data (e.g. date, time, domain, user IP, analysis A/B/P, PDF, invoice, etc.) in backend (table with filter) and send e-mail with these data to us too. 8.) Check how the data of the existing "Analysis A" are gathered by the script (what is the data source. 9.) Ensure that frontend and source code are white label (only our name and domain are visible). There is a draft (scheme) attached to describe the tasks in a simple way. You may consider our proposal and send us your consent or your suggestions. During a chat we can discuss any questions and details, of course. A detailed project description will be sent to you too. The suggested budget for this order is: 500 $ - 800 $ Please observe the following terms of our cooperation: 1. You confirm to keep any information and data related to the project, website, business strictly confidential. 2. You also confirm not to contact our users and clients directly (neither now nor in the future). 3. After launching the order you agree to exchange your contact details with our company at once (i.e. before handing out any credentials to you). Mandatory data we need from you: Your E-Mail, Skype, mobile phone number, full name, full address. Otherwise the contract is terminated by us. 4. You ensure a fluid workflow and you are available by Skype. 5. You are qualified and available to work on our project. Professional skills and deep experience in Laravel, PHP, HTML5, CSS3, MySQL, jQuery, Linux/Plesk, payment integration (Stripe and Paypal) are required. We look forward to working with you.
