Possible opportunity

So I’ve recently started DJing on a rev 1 for about 2 months I think I have solid mixes but I heavily rely on stems my eq work just isn’t there yet. But this past week I did my first party it went really well had crowd dancing and vibes were there, met a promoter and getting me a opening set at a club is in the talks. My problems are I’ve never touched a CDJ and not too confident in my ability’s if I don’t have stems to save me haha. With that being said I don’t know if the move is to better my skills and let this opportunity pass or take and learn from it.
