I think the main things that would make a big impression in online dating is a good profile & appropriate photos. As I was doing my research online, I came across Profile Helper who offer the very service that I was looking for.
I got in touch with Eric Resnick over email initially and he answered all my questions & clarified my concerns before I signed up for their Premium membership. He was very generous with his time during the appointment, which went on for almost 2 hours. He went through all the relevant stuff in detail, answered all my questions. It was in-depth coaching right from how to search to first date. He also asked all the right questions so he could get a good understanding of me & what I am looking for. Then as promised, after a few days, he sent me the profile write up. It was very well written, he had captured & articulated very well; both who I am & who I am looking for. He was also happy to make appropriate changes as we fine tuned, going over it couple of times. Further he also reviewed my photos & provided very good guidance on that front too.
Over all I am very satisfied with my experience with Profile Helper and highly recommend them.
