Hibiscus seeds can most certainly be started indoors during the winter in preparation for spring planting.
To grow hibiscus from seed, sow indoors 12 weeks before the last spring frost date. Soak seeds before sowing. In terms of when to plant indoors, you should go to our frost dates page (https://www.almanac.com/gardening/frostdates) since dates vary depending on location in Zone 7.
As far as container to start your seeds in, just about any container should work as long as it has drainage holes.
