A simple logo designing that already exists but needs improving

I need a designer to improve this logo for me at a low cost as I am starting up. We want to use a logo very very similar to the one we have created and that is attached as our customers are used to it but also it has just been printed on our thank you cards. Minor tweeks will be ok but we can;t overhaul it.

The reason for the creation is that we have worked on a screenshot version up to now but we need high quality files to help us improve on social platforms
