What are a few options i should consider to pursue in university? how long will it take?

i want to try my best to avoid having to take a levels, i want to go straight into foundation if that's possible. my best subjects are maths and english. if it's possible, i would like something that would require me to socialize or get out a bit, i don't want something mundane or something that comes with a cubicle. my computer skills are decent. i don't take art at school, i'm a science student. however, art does fascinate me and i think i would quite enjoy it if this job involves a little art, but if it doesn't, it doesn't matter either. i like children and my heart reaches out to the disabled/homeless/abused, i don't mind something that would involve them. i also don't mind something along the lines of construction. i don't want a job that will make me travel alot, cos i plan to have a family in the future and i want to spend time with them, not always having to be away because of my job. i would like something with regular hours, not something where they would call me in to work in the middle of the night.
