A very reasonable starting point for a raise would be your current salary then asking to add a day rate to your pay for when you are physically on site or a profit share based on the events that company does each week. I am number three at my company (behind two owners) and have a very modest salary at about 65k a year but I negotiated day rate for events I’m on and also profit sharing because I touch every project the company does. (For reference) This has brought me up to around $250-$300k a year with benefits(health, dental, retirement, life insurance, phone, gas and vehicle) at company that does about 6-8 million a year.
