Do online (paid, not free) in depth consultation even exist?

I have called a few accountants that list "consultancy" as a service because I have several question that I need to go in depth that can not be handled but the classic "free 30m consultation"

I have offered money for an in depth consultation but every single time all accountancies want to sell me a whole package and dont want to do a "one-off" consultation

I won't need a full package accounting filing etc, my business is super straight forward, I buy and sell, keep receipt and do the calculations easily, booking is fairly easy.
yet I keep getting the same transcript line "we value long-term relationship only" copy paste

I can't seem to find in depth consultation, or business planning, as a service
does it exist? any reccomendations?
Im happy to pay for their time obv

context, Im sole trader online seller opearing with marginal VAT who wants to move into an LTD with already a lot of owned inventory
