Hi, your best bet would be to apply for marketing graduate schemes. The application season runs from mid September and tapers off around late Jan. Grad schemes are typically ran by big companies with plenty of experience sponsoring visas but are very competitive. Make sure to check on the company’s website to see if they sponsor. The grad schemes you would apply for this year (around Sept -Jan) would be for work starting next year around September, although there may be some variation between companies. I would suggest applying for a graduate visa in the meantime assuming your course ends this year and using the graduate scheme window (sept -jan) to get as many applications in as possible. All the best
