If you are just starting out, I recommend these marketing tools: logo, business card, thank you card, and/or flyer.
If you need to redo your website layout to a new + improved layout, or want to improve on the experience of your brand, inquire for a revamp.
If you need to promote your brand at a pop-up event, inquire for business cards, or a digital business card.
If you need a simple logo, inquire for a text based logo.
If you want to take the extra step in creating brand recognition, inquire for merch designs.
If you want to promote your brand in a public area, these are the pop-up shop necessities you’ll need: business cards, flyers (promoting a deal, service, or product), sample products for product-based businesses, a table with a table cloth that goes with your color scheme (or a designed table cloth), preferably a tent for sun protection/a rainy day, custom bags, a price list.
