Dear Harsha,

To build an online panel for market research purposes you should
consider, amongst the others, issues about:

 statistical inference of the results derived from the panel to any
larger population. From the selection procedure you propose there will
probably be autoselection bias in your panel - unless you recurr to some
alternative model, like respondent-drivensampling or propensity scoring.

 incentives: I see that you planned a price draw, but have you also
considered charity donations, discount coupons, and the like? Not all
survey participants have the same motivation to do so, and by allowing
multiple "compensation" alternatives you are more likely to gather a
less biased sample of internet users

 maintenance: trainig/retraining scripts, rotation/replacement
schemes, quality control issues, etc...

Should you require further assistance I will be to share with you and
your university my experience in panel building and maintenance.

Kind regards,

Mr. Luca Meyer
