As a native English speaker, I find it difficult to understand what you have written because your grammar and punctuation (which are important components of the language) are poor.

If I understand you correctly, you would like someone to create a vanity address generator that returns a number, N, such that a private key derived from SHA256(M|N) has an address that matches a pattern, where M and the pattern are both chosen by the user.

That is certainly doable. Is there a limit on the value of the number?

Keep in mind that as others have mentioned, any brain wallet is insecure. That includes your derivation of a brain wallet. While "now is the time for all good men to come to the aid of their country 67854897" is more secure than "now is the time for all good men to come to the aid of their country", it may not be not secure enough to be used as a private key.

my first paragraph in my topic literally comes from https://en.bitcoin.it/wiki/Deterministic_wallet have grammatical errors? lol really for a native speaker I expected better even non native illiterate person would understand what I wrote in simple English people don't have to know English to understand it second many programmers don't know English but can write programs using it for if for and while loops besides this is not grammar and education measuring contest
