Social media needs to become your best friend as some others have already said…Linkedin, Snapchat, Facebook & all of the rest…use them to the max. You also need to do some homework and email as many transport firms as you can with a pdf of your offers they can look at/print off. Make your website as user-friendly as possible & deliver your orders as quickly as possible. Promise to get orders out within 24 hours and figure out how to make that happen. If mum is working on the firm get her to answer the phone and publish your number.
Long warranties - forget it, especially on bulbs LED or otherwise, reduce the warranties & the prices accordingly.
I used to run a business with a website and it brought us 80% of our work…websites & social media rule now…do not underestimate this.
Your products & prices look great!
Best of luck.
