4 months to lose 6kg

My pre-pregnancy weight was about 63kg and I was size 8-10 (I was doing the gym and getting into shape) Then I stopped exercising whilst pregnant and I'm size 12-14 and 71kg. We are going to holiday in April and I'm back to work in March, I really don't want to buy a whole new wardrobe or go to holiday feeling as I do now so I'm looking for anyone that can help me create a workout program that I can do from home with minimal equipment but also maybe do the same exercises at the gym if I'm able to start going again. I don't mind paying for the program of course but I'm really struggling to find a PT that understands pp fitness and can help with this. I'm looking for a bit of dirt and nutrition advice too. I'm hoping there's someone out there 🙏
