There are some conditions which should be met for a marriage contract to be valid, the most important of which are the consent of the guardian and the presence of two witnesses. For more benefit, please refer to Fatwa 83629.

However, it is not permissible for you to go to places of disobedience and sin even with the intention of looking for a girl in order to approach her for marriage; having a good intention does not render a evil deed good or permissible; for more benefit, please refer to Fatwa 84281.
Therefore, we advise you to endeavor in looking for a pious wife, and you should not despair, as you may find a pious woman whose parents and herself would be pleased with very little marriage expenses.
