What do i do do i pick a budgie or do i take the society finches and wait?

this is the problem i have 2 society finches and my parents do not allow me to have any more birds so i have to get rid of these birds because i want a budgie. but the problem is i have grown attached to these birds and the problem is that these birds are not messy but budgies are but i want to be able to get birds and keep them for a long time. but if they are messy i wont be able to. plus i want a companion bird like a budgie but i dont want to have to lose them what do i do. oh and please dont tell me about another bird i only want either budgies or society finches. thnak you
