Build a Website -- 2

I need to add to my AWS server the website with a form in order to work with facebook developers in order to post in differents groups for 30 seconds intervals in order to not be banned, I need that this app works with all the user that request the service, please consider to add paypal code in order that user who pay the service can get it and post in different groups walls. The form needs to be easy for the users (UX) just to add title, attached image and description. Please send me your idea and your propose in order to valuate to get the best candidate an ETA to finish the project. I will provide access to my server who gets the Job, the only thing that I´m going to need its your public IP to added to my inbounds rules.
