Would you be kind to advise on which sector you operate and how many companies are to be called or how many hours of work are expected so that a bid can be placed accordingly as you have a fixed price budget.
Presumably you will supply a list of the suppliers to the successful bidder along with an idea of the kind of prizes you are hoping to obtain from the suppliers.
Approximately how many suppliers are there? Do you have a particular deadline for this task to be completed?
Could you please clarify a couple of points; firstly approximately how many suppliers will need to be contacted and secondly will the cost of the calls be reimbursed or should this be included in the fixed price bid?
Keep in mind that you have more chances to win a Job with Case Study as fewer Sellers will send a proposal. Moreover the Buyer has already paid a fee for it, which shows that they seriously intend to award the Job.
