Read about storage
Most companies have door to door services but you can get a company that allows you to pack at your own pace. This means, the company will deliver and leave the storage boxes with you and you can fill them up at your own time and convenience. Then after you have finished and whenever you are ready, just call them for the best time for pick up. That is the only time they will pick up your storage containers. When you want them to deliver the container is also something you can specify.
