To hire a consultant and not to hire is a personal choice. A well experienced, learned and reliable consultant (if not subscribed to this forum for information

) could be a nice addition, and free life as long as every information is provided.
My advise, just relax, the procedure is as follows:
--- You get ITA
--- You start filling detailed application post ITA.
--- You will have to fill the 10 years history, personal history, travel history, address history along with many other details.
--- You will have one placeholder to upload multiple documents. (you could have 5 Police clearance certificates, they all are to be scanned and merged as a single document of less than 4MB size and to be uploaded in ONE PLACE HOLDER assigned for it)
Start doing following:
1. get all your documents scanned
2. Proof of funds shall be issued in the lasy only once you are ready to submit the application.
---- If you have 3 jpgs, you can convert them to pdf using online tools (or if you adobe acrobat professional, cute pdf writer) etc.
---- Then you can select the pdfs to be merged and set there order, and scan them as a one file.
