to qualify under Category 2 (Arranged Employment), you need to get an offer approved by HRSDC and attach to your file. You file status in London will be changed from Cat 1 to Cat 2.
You employer needs to be on the list of apprved employers on HRSDC list and your particular job offer or employement status needs to be stamped by HRSDC for this.
without HRSDC, you will qualify for Cat 3, which needs you to have been in Canada for at least 1 year and also gives 5 points. but, that i guess is still 8 months to go.
talk to your employer if he's willing to hire you on a full time basis and do a little bit of a running around HRSDC for you. It sure will work out.
All the best.
