I would like to hire a Joomla Developer

Hello, I would like to set up an external website to attract customers with a blog and some marketing information, those 1 page scroll type, with some cool layout features. Then on that page I want people to sign up for a paid subscription for 1 year with a max amount of users. A counter would be nice to show the remaining spots. Then when registered and paid a training starts which takes about a year and content should be published weekly in multiple (about 8) categories. The homepage (after log in) should show all newest content of the current week. And for each category you can view all published content. When a new group starts they start in week 1 again but follow the same path. Most sections will be quotes, text, video or sound bits. Some are a little more complicated I want a section where the user can ask questions to their coach and gets response. And one category is a section where questions are asked where answers need to be filled (text), which will remain. I also might need a section where feedback documents can be uploaded by the administration for the user. I have a designer but without joomla knowledge would need support in that as well. I think reoccuring billing options might be needed for people who will not pay in one go. I would like all content to be accesible by mobile device. And I would like a trick to aoid the video & audio content to be downloaded, however it would be nice if they can watch or hear it offline. I am posting this, because I am curious about what kinda of pricing would be appropriate. And if that fits my budget I am very interested in establishing a long term relationship to support me in this project. We have been working on the content for 5 years. And we think we need one more year to finalize and set up this system. Thanks a lot for your time already and take care, Rose
