"Marketing Consultant" (not I.T.) - rate?

[ChimpMaster]

OK a bit off topic (i.e. not I.T.) but tomorrow my wife has an interview for a Marketing Consultant / Contractor role for a big construction firm. We have no idea what kind of rates these roles offer as she has been a permie Marketing Assistant/Manager at a salary of £30k - 40k.

I'm thinking she should go for £300/day but that's just the optimist in me speaking. Does anyone here have ideas on what rates independent Marketing Consultants can demand?

(of course I'll do my own research but time is limited and your opinion is oh so valuable etc...)

No idea, but general rule of thumb is take annual salary divide by 1000 and that is the hourly rate so 30k is £30 per hour = £240 a day. £40000 is £40 per hour = £320 a day.
