Hi dear, I have taken a look at your website I can tell you right away as a designer that there's more to do on the frontend. Firstly, it looks plain green and not very appealing. It is also clustered and may affect bounce rate as many prospective buyers wouldn't like to look talk less of stay on a clumsy site. Secondly, the store needs to be redesigned to look like a modern educational website that appeals and encourages buyers to stay and learn. Thirdly, as a writer, I will be glad to develop the blog section where science-related materials can be posted to boost your SERP and Google visibility. I have more I have seen that could be reworked but I'll need you to message me so we can talk further. Thanks! Remember, you need not just anybody but a cool-headed lady who understands website design and can work with you for this.
