This will be an ongoing project that will need to be maintained, updated etc.
The best way to describe what I want is through examples of other things that have the same functionality. I'm looking to develop an android-like system in the following sense:
I want my users to have a "homescreen" which they can populate with "widgets." These widgets will do a variety of things such as: time zone converter, calendar of events, content/RSS streams and other custom stuff. Some content will come from my network of sites (a WP multi-site installation) and some content may come from the users' own eg, RSS feeds. New widgets and functionalities will be developed on an on-going basis depending on user feedback, company objectives etc.
I want the user to be able to drag and drop the widgets and receive instant functionality. For example, http://draw.io allow you to pull shapes from a ribbon on the left, drop them on the canvas and the resize and edit accordingly. This is the functionality I want with the widgets. Drag a widget onto the canvas, set some parameters/filters, size it how you like, click save and start using immediately. I don't want the cumbersome WP process of "Save Draft" --> "Publish" --> Go to website.
The "dashboard" of Infusionsoft CRM also does what I'm looking for. When I log into my Infusionsoft I'm created with "dashboard" that is populated with "widgets" that I selected that provide me various information that's of interest to me. The only problem with Infusionsoft is that the widgets aren't drag-n-drop. I have to click to bring up a list, click to select and then click and drag to move it where I want. Too cumbersome.
Everything should be responsive. Mobile is a must. Perhaps in the future, I'd consider a native mobile app, but at this time I don't think it's necessary.
Feel free to contact me to set a time a chat and I can give a broader picture of my business goals, the 4 stages of development we have and how this system fits in to all of that. I can also give a walk through some programs that have pieces of the functionality I'm looking for.
Time frame is on-going, but there should be clear milestones and stopping points (eg, system development and 5 working widgets).
Budget is negotiable. I want the best product on the market. If you can justify your cost, then that's what it is.
There are also opportunities for other projects if you have an entrepreneurial spirit. My company has quite a few websites, e-commerce sites and some other interesting custom platform development work for projects that we're incubating. It depends on you and what you're interested in doing.
For the right freelancer (or team), there is lots of ongoing work available.
Payment terms are flexible. I imagine in the beginning we'd have a fixed price up to some clearly defined milestone (we need to test each other out and make sure the relationship works). After that, most likely, we'd want to negotiate either a monthly retainer to carry out ongoing maintenance, updates/upgrades etc., as well as (possibly) work on developing other projects.
Payment is really something that should be discussed as many different models are possible.
