Use the online tool and do some research yourself. No need to pay a consultant to use a website that you can do yourself. Many consultants provide incorrect information, bad guidance and make mistakes when filling out applications which can lead to severed consequences (like a 5 year ban) so it is important to educate yourself so you know if a consultant is providing you with good advice. You can also apply without the need of a consultant which many people do. How old are you, what degrees have you done since you completed secondary school, what have you been doing for work in the past 5-10 years?
