Costs:-
There's no definitive answer to that. Various sites will offer various packages. Some will be 'packages' of assorted sizes and durations. some will be more like a pay-as-you-go system. Ultimately the total cost will be up to you as YOU are the one who will decide what package to take and how often you use it.
Good luck - it's a fascinating subject. 
There are restrictions on what information can be found via on-line searches:-
Births - 100 years or more ago
Marriages - 75 years or more ago
Deaths - 50 years or more ago.
Censuses - 100 years or more ago.
A personal visit to a 'records centre' can elicit more recent information.
On-line images are not considered valid for legal purposes, but you can generally get a 'hard copy' for a fee, this WILL be considered legal.
