Hi, I'm currently a front-end developer and don’t know how to setup a professional backend for future web dev clients. After a customer agrees with their quote, I as the administrator would like to send the customer a username and a password so that they can access a backend portal. In that backend portal, I would like that both I and the client could share content with each other. I plan to select forms for them to complete and return with a timestamp. In the portal, I also plan to receive and validate payments that I charge the client. I would like there to be flexibility and automation because some would prefer monthly payments. In the portal, the client will also have the ability to oversee the website I am developing for them in the directory. Last but not least, I would like the ability for I and the client to create and edit a portfolio page (if they want to) from the portal. Some of this probably sounds very confusing, but we can communicate and straighten out the mess. I have most of the front-end development live and running. Only bid if you have the skills to handle this.
