WHMCS Domain Registration PDF

Hey, guys. I'm looking for people for the following work: Unfortunately, I couldn't solve it, so I need your help. I would like to create a module for WHMCS that is inserted into a template based on client data to create a PDF, send it to customers, and the client can download it back to us via WHMCS. Specifically, it would be necessary for domain registration. So the client submits the order, collects the domain owner data (including the name server), creates a PDF based on it and sends it by e-mail. You know, the client will sign it, and you can send it to us via an interface, and the system will send us an email. It would be great if the client could manage these documents through their own interface. So you can see the domain and, for example, click the button next to it to download documents and statements. And if you could get the documents back there, that would be the coolest. I would work with the developer in the long term, as I would also need to integrate possible future documents. I'll send you a sample of what our domain registration form looks like. Thank you for your offer in advance! In case of questions, seek confidence! Richard
