  • hình của jamesnicol Re design our website £1700.00 GBP

    “Lena is great. Our project was awkward and required a number of features that didn't integrate easily. Lena was able to transfer most of our requests into website attributes; when we wanted the impossible she was clear on what could be done, and what couldn't be done. We are very happy with the result, and she was very understanding when we 'flip-flopped' - something most people would get annoyed about.”
