Your request can be fulfilled, but there are a few things that need to be clarified.
First, your measurements need to be taken. You can send a picture if you don't have someone to measure you in Nigerian style clothing (also, a picture of someone representing your stature can be sent if you do not want to send your picture).
Next, you need to state the colour of the outfit you want and quality of material. This would determine the cost to a large extent. But given your budget, I have an idea the kind of material that would be suitable.
I noticed you mentioned Agabda style, meaning you're male or the intended wearer is male. If that's the case do you want the full Agbada or half length (popular with young guys these days)?
Do you have the cap to be worn? If not, I can also get a cap made. I'll need to know the colour picked for the occasion and your head size.
As regards, getting the cloth, will you be coming to Nigeria for the wedding? If yes, where will it be holding? It can be delivered to you. If you're not coming to Nigeria, it can be sent to you via DHL or FedEx on priority shipping to get to you next day. This cost will be borne by you however.
I hope we can work together given the tight deadline.
I look forward to your response.
Cheers.
