You can get yourself a tutor online- plenty of options available. One good option is iTalki- tutors for all kinds of languages on there. They'll be happy to take you through whichever curriculum you prefer e.g. Madinah Arabic or bayna yadayk etc. Obviously it has a cost but I would say it's worth it- and the community tutors there are usually cheaper.
if you want to learn on your own then you can find many courses on youtube, or you can watch videos from lqtoronto.com, a very good course for beginners.
