Signing up with a matchmaker is more than just making a decision and then just forgetting about it. Your job doesn't end with the signature and if you haven't yet found the person, it might be wise to keep your profile updated so that you find someone eventually. An updated profile will get more attention than someone who has just signed up and then not bothered to change anything even after a year or so. After all, imagine yourself in the same position; you wouldn't want to be involved with someone who is too busy or too lazy to even update their own profile.
Once that is established, the next thing is to build on your profile itself. Now, you need to remember that your profile should be flexible and should have some wriggle room. If you are too uptight about your requirements, you are bound to stay single for a long time or even for the rest of your life. You have to work on keeping a flexible profile and perhaps even listen to suggestions, from the right sources. If your matchmaker feels that you need to change something about yourself, you are better off listening to the suggestion and working on improving yourself to be a better catch for the opposite gender.
Next, decide beforehand how much you plan to reveal about yourself. There is a basic minimum that all matchmakers expect you to disclose if you want to have successful dating. But, beyond that point, it is entirely up to you to say anything additional. If you feel that you have some particular quality or trait that has an effect on your dating life, then you should definitely reveal that before it reveals itself in an embarrassing manner. On the same lines, if there are some specials requests or something important you are looking out for in your dates, then perhaps you should make it known before the matchmaker goes about doing their job. It doesn't matter how good or bad it may be; if it affects your relationships, it should be known.
Your matchmaker will help you out when it comes to building your profile. Of course, no matchmaker will leave you in the lurch and expect you to do everything on your own. With a smart and suave profile, you should be able to automatically get more dates without any difficulty.
Your profile can be one of the most important aspects of your matchmaking experience. Many people find themselves tempted to bluff a little on their profile but it makes it way back to them. Keep your profile honest and true. You want the first date to be a confirmation about what you put in your profile not the opposite. A successful relationship is built on trust so you don't want your first impression to be one built on mistrust. If you want to make the relationship that your matchmaker finds for you work, then begin with an honest approach to your profile.
