I am sorry but you can't say 'with all due respect' then take that tone. All the advise you have got so far is spot on, there is plenty of piss taking and trolling on the forum but I don't see any going on in this thread, yet.
Please be aware most of the people that have responded to your thread have many years of experience, both within the industry and posting here to DIYers.
Your questions are currently a bit vague, hence why people are suggesting you find a proper installer.
Maybe if you break down what you need to know if you are certain on a DIY route.
Yes, if you wish to swap your panel for a Premier 24 that would be fine, but you may find the issue is not the panel.
If you wish to take on installing the COM modules to the Premier you will need good IT knowledge and be able to understand firewalls and port forwarding.
As I say there are plenty of threads within the DIY section that have had DIYer's asking for help with there installation over a period of months to get a partly working system.
They are worth a read, many questions have been answered time and time again.
