I need a Power Apps Developer/Support agency

We have developed, in conjunction with a local (Australian) developer, a Power Apps-based operating system for our Primary Production business. This software incorporates Model-based app, and several Canvas Apps for various components of the overall functionality. Additionally, we are utilizing Power BI for reporting. The system/solution is currently in its final stages of initial testing and deployment, although it is anticipated that the solution will continue to evolve and continually develop and improve.

We now require ongoing support in terms of Power BI report writing, snagging, ongoing maintenance, and further development. We are seeking an offshore resource to take over from the local consultant in order to manage the overall ongoing support and consulting costs. We are based in Australia.
