Dear Querist,
1. Quashing of FIR is done on specific legal grounds as laid down in Bhajan Lal's Case, these are
8.1. In the exercise of the extra-ordinary power under Article 226 or the inherent powers under Section 482 of the Code of Criminal Procedure, the following categories of cases are given by way of illustration wherein such power could be exercised either to prevent abuse of the process of any Court or otherwise to secure the ends of justice, though it may not be possible to lay down any precise, clearly defined and sufficiently channelised and inflexible guide- myriad kinds of cases wherein such power should be exer- cised:
(a) where the allegations made in the First Information Report or the complaint, even if they are taken at their face value and accepted in their entirety do not prima facie constitute any offence or make out a case against the ac- cused;
(b) where the allegations in the First Information Report and other materials, if any, accompanying the F.I.R. do not disclose a cognizable offence, justifying an investi- gation by police officers under Section 156(1) of the Code except under an order of a Magistrate within the purview of Section 155(2) of the Code;
(c) where the uncontroverted allegations made in the FIR or 'complaint and the evidence collected in support of the same do not disclose the commission of any offence and make out a case against the accused;
(d) where the allegations in the FIR do not constitute a cognizable offence but constitute only a non-cognizable offence, no investigation is permitted by a police officer without an order of a Magistrate as contemplated under Section 155(2) of the Code;
(e) where the allegations made in the FIR or complaint are so absurd and inherently improbable on the basis of which no prudent person can ever reach a just conclusion that there is sufficient ground for proceeding against the accused;
(f) where there is an express legal bar engrafted in any of the provisions of the Code or the concerned Act (under which a criminal proceeding is instituted) to the institu- tion and continuance of the proceedings and/or where there is a specific provision in the Code or the concerned Act, providing efficacious redress for the grievance of the aggrieved party;
(g) where a criminal proceeding is manifestly attended with mala fide and/or where the proceeding is maliciously instituted with an ulterior motive for wreaking vengeance on the accused and with a view to spite him due to private and personal grudge. [305D-H; 306A-E]

2. Fees depends on the lawyer, there is no fixed fees.
3. If chargesheet is not presented - Only FIR would be seen and in extreme cases the Case Diary. if the SLP is admitted the State/Complainant get to file their counter affidavits rebutting one's claim.
Good Luck !
