Hello. I am a full stack laravel developer. I will build you a url shortening site with several key features. Let me tell you how its made.
First of all i will use Laravel framework with php language, along with html, css and javascript. The frontend will be a modern and beautifull design, including the user dashboard. The user can register and short urls or he can short urls without registering, we can tweak them based on your wishes. I will also add captcha protection to not reward bots and losing a ton of money. Regarding the payment, i can code for payment using skrill, paypal, bitcoin, web money etc.,
For managing the site, you will be provided with a hidden url. The url has several statistical information's, user details, approve payments (Important part. I can automate payments. But i would suggest using manually approved payments.), lock users, ban ips etc.,
Total work takes lots of time and dedication. I am estimating around 8-12 days for complete delivery and the price will be 750 usd. I will be in constant touch with you and show you a demo frequently and tweaking it. You will be completely satisfied with the end product.
Thankyou for taking time to read my proposal. Please contact me if you have any queries. Looking forward to working with you.
