Hi There,
Greetings !!
We have a team of 25 full time, dedicated developers having expertise in iPhone, Android, Joomla, Magento, Wordpress & Core PHP. We are willingly to work on this project.
We can customize components, modules and plugins from the scratch as well as integrate and customize 3rd party extensions too.
I've briefly referred project requirements & found feasible to implement.
Our services are fully tailored to your business and we do take a little time to understand your objectives which will give you a real edge over your competitors and receive a special and personal service.
If you can reply us with detailed specifications, it would help us and we can estimate the development time properly.
I think, I'm understanding your concern & advisable is not to modify standard Joomla admin.
Normal users or registered users would not be able to access them.
Instead of making a simplified Joomla admin, we can make an easy interface for users - so they can login on front-end & can design K2 form they want.
Modification on default Joomla admin would be too much complicated to address.
Let me know if you think the solution I shared, can be workout with more specification/details.
We will surely address project requirements, exactly as you want.
Please communicate your feedback & allow a small discussion to conclude the flow.
I look forward to have a prompt response from your end.
Thank You.
