Bidding help

Looking for advice on placing my first bids. I’m located in Tx and was advised to keep the hourly rate for techs at 65/ hour when bidding projects. I’ve received a list of Walmart Supercenter remodels that I need to bid on. Should I keep the hourly rate for a spotter the same as the 65/hour Lead Tech rate? Or rather, should I lower the spotter rate? If so, are there any suggestions on what rates you recommend bidding your techs and spotters out at? I’m trying to win as many bids as possible. Thank you in advance!
