In pursant to the query raised by you, i wanted to inform you that getting the trademark registered for your business is always a good option as that limits the other using the same trademark. Today you might be a small organisation but if you grow up at the later stage then the goodwill of the organisation does matters in the eyes of your clientage and the same is displayed by your brand name.
As an IPR practisioner i have seen many of such cases wherein there are many similarities of the logo of the companies and the peole tend to get confused beacause those brands are created to get the clientage of those brand who trust the original one.
There are many legal compliances which are required to be done but then it will depend on the turnover as the registration under VAT or Under servic tax depends on the total sales and the place of your business.
