hi! if you’re looking to apply for a job, i would recommend looking on linkedin rather than indeed, or by going on company websites and finding their careers section (if they are big enough to have one). i applied for a part time 8 hour job at fatface and its great in terms of pay. regarding a small business, i am currently running a graphic clothing shopify store using printify, where they print your designs, store and ship the products to the customers, so i dont hold stock or make the items myself, i would say this is a good way to make some money as all you need is simple designs ( think pinterest, procreate, canva etc ), and to set up a website which you can do for free via etsy, or by paying £5 a month for shopify. from there, you just need to advertise it on socials then you’re good to go.
hope this helps as a fellow college leaver x
