info on upgrading 99' GTP for a customer

one of my customers has a 99' grand prix gtp supercharged. he is wanting to do a good bit of stuff to it. i have found this company called ZZperformance.com they have alot of items for these cars but unless i do a $1500 buy in i get no discount. in 10 years of moding cars this is the first grand prix i have been asked to do so i cann't justify doing the buy in. TWO QUESTIONS:

1 if i were to do the buy in would you guys be interested in purchasing upgrades from me, from this company?

2 does anyone know of any other companies that offer performance products for these cars?

thank you for all of you help in advance.
