woocommerce how to limit products

hi

is it possible to limit the number of products one can list when i use the pro sites plugin, for example i would like the following levels to limit the amount of products they have for sale. eg:

level 1 (free) 5 products
level 2 ($10) 25 products
level 3($20) 50 products
level 4($30) 75 products

how do i go about to acheive this

thanks
