The following webpage contains all the information he will need. He can apply online.
You can either prepare a letter yourself or ask a solicitor to prepare a sponsorship declaration for you. A declaration would cost around £50+Vat and is the ideal document to submit, but usually a letter from you would suffice.
The letter/declaration should include the following:-
The letter should be submitted with his application.
The visa will be granted for 6 months. He must leave before the expiry of this.
It usually takes between 4-6 weeks from the date of the application to receive the visa.

The sponsorship document should suffice. He should submit evidence of the funds available to him and the sufficiency of these to cover the costs of his stay. He should also produce evidence of his job in Turkey and also any accommodation he rents/own to corroborate the fact that he is to return there.
I should also say that he is not permitted to undertake paid/unpaid work whilst he is here on a visitor's visa.
Hope this clarifies, if so please click accept.
It helps if he has a job, but it is more important that he is able to show that he can support himself while he is here. If you are to provide accommodation then the money required is less obviously but he should demonstrate that he does have access to his own money for emergency purposes.
Please click accept, I will continue to answer your follow up questions.
If he is to stay with you and you are to pay for his food and accommodation then you should also show the monies available to you.
There is no fixed amount for working out the money available to him, but I should think somewhere in the region of £200-250 per week would be sufficient.
