That's a very helpful situation. I wish you [and your colony] all the best. You may consider contacting your local Beekeepers Association. Some are better than others, and a good one may have a decent, experienced member who would come out to offer support.
With the empty kit, now is a good time to ready it for 2025 use. If the hive with colony threatens to fall apart having solid options to transfer frames into may be helpful come April onwards [weather permitting]. Also look around for super boxes and frames. A healthy colony will need more than one super once the season gets going. Be aware that on this forum there is plenty of discussion about suppliers in terms of quality, value for money etc.. Second hand kit is more hazardous than buying most "used" things so, at present, don't dive in.
