All the information you need about visa options and applying for visas can be found on the UKVI website, or here on the forum.
So feel free to ask anything you like here and we'll be happy to help.
There should be no need for a lawyer at all unless you believe there are real, serious reasons why you might have your visa refused, such as if you have serious criminal convictions or you have previous bad UK immigration history, such as refused visas, refused entry to the UK, illegal overstaying or illegal working in the UK.
