Look at zone 2, max zone 3 further than that is not really London the way I see it. You may be able to get a studio flat for around $1100-$1200. I have a flat in zone 2 for when I am in the UK, two bedrooms, and it sets me back with £1600 per month that's around $2400, you also have to pay council tax which is quite high, I pay around £150 council tax per month for that flat so it's really £1750

Keep in mind that London is expensive. If your online adventures don't generate substantial amount of cash you may want to look into getting contracting jobs as a designer/programmer while you are there to fill up the gap. There are contracting agencies that will manage your schedule and find the gigs for the days you want to work. I have many friends that work trough such agencies 2-3 days per week
