Look for a Southampton immigration solicitor or adviser with experience in the type of application you need, such as a family visa, work visa, asylum claim or settlement application. Check that a solicitor is regulated by the Solicitors Regulation Authority (SRA), or that an immigration adviser is authorised by the Immigration Advice Authority (IAA). Before instructing anyone, ask about their fees, likely timescales, services included and relevant experience. You can also compare their advice with the latest information on the official GOV.UK immigration pages.
