Praise be to Allah (The Glorified and Exalted).
You may seek a husband by attending a certain masjid (mosque) frequently, and making sure to introduce yourself to the other sisters. When you have gotten to know some of the sisters well, tell them you are seeking a Muslim husband that truly practices Islam, and you would like them to ask the other sisters they know, to see if one of them has a brother, etc that desires to get married.
You may also speak to the Imam, and ask him if he can help you find a husband by asking some of the brothers privately whether they desire to get married. He may also make a general announcement, asking the single men if they would like to meet with him after Friday congregational prayer, so he may speak to some of them about the prospect of marriage. Make sure you make it clear to the Imam or sisters, the type of Muslim husband you want to marry: age, occupation, religiosity, character, where does he live, etc. Then you can have a meeting arranged with the potential husband, in the presence of the Imam, in which you can ask him certain questions, before accepting marriage. This is much better than the corrupt internet websites, in which men and women shamefully speak to one another with no regard for the Laws of Allah (may He be Glorified and Exalted) and in which the women have no Muslim male guardian present, and their photographs prevail over the internet for all of the world to stare at.
Because you come from a non-Muslim family, you are also in need of a Muslim male guardian to help you arrange your marriage contract, this position can be filled by the Imam or some Muslim man part of the Masjid board. This person will be present when you speak to the potential spouse, the guardian will help you to secure your dowry and compose your marriage contract, and will give you in marriage to your future husband by saying, "I give so and so in marriage to you, do you accept." Two trustworthy Muslim male witnesses are also required to be present during the signing of the marriage contract, these cannot be family members of the husband, they must be unrelated and one cannot be your guardian.
Finally, make a lot of Dua (supplication), especially during Tahhajuud (3:00am prayer).
And Allah (The Glorified and Exalted) Knows Best.
